Principles of stellar evolution and nucleosynthesis by Donald D Clayton( Book )
42 editions published between 1968 and 2007 in English and Italian and held by 884 libraries worldwide
The fields of stellar evolution and nucleosynthesis comprise one of the most vital and intriguing areas of modern sceintific research. The recent build-up in the space exploration program has been accompanied by a new surge of interest in the physics of natural phenomena. Since stars are the most common element in the universe, much of our knowledge is moderated by our concepts of their structure and evolution, and the synthesis of elements from which they are formed. This is the first text to present the basic physical principles of stellar evolution and nucleosynthesis. The book provides a clear statement of the ideas which dominate modern research in the hope that it will attract more students into this exciting field. By concentrating on the physical principles, the author has attempted to clarify the theoretical ideas which will prove valuable in a wide variety of future problems. (Author)

Nucleosynthesis of heavy elements by neutron capture by Philip A Seeger( Book )
4 editions published between 1964 and 1965 in English and held by 6 libraries worldwide
Nucleosynthesis of elements heavier than the iron group by neutron capture on both slow and fast time scales is evaluated. The s-process calculations of Clayton, Fowler, Hull, and Zimmerman (Ann. Phys. 12:331, 1961) were revised to include more recent experimental results on abundances and neutron capture cross-sections. The solar-system s-process abundances indicate a history of neutron exposure distributions characterized by decreasing probability of high integrated flux; an exponential exposure distribution is extracted. Estimates are made of the s-process contribution to each isotopic abundance; a table gives the amounts of elements produced by each process in the solar-system material. The r-process calculations are carried out using a semi-empirical atomic-mass law to determine neutron-binding energies and beta-decay probabilities. The solar-system r-process material has probably been synthesized in two distinct types of environments. (Author)

Estimating Starburst Supernova Rates Using OSSE Observations M82 and NGC 253 ( file )
1 edition published in 1994 in English and held by 1 library worldwide
We have used the OSSE observations of the starburst galaxies NGC 253 and M82 to obtain upper limits to the Type Ia and Ib supernova rates in these galaxies. Monte Carlo simulations of randomly occurring supernova events in NGC 253 and M82 were performed to evaluate the significance of our upper limit to the 0.847 and 1.238 MeV 56Co gamma-ray line fluxes on the supernova rate from these two galaxies. A set of observations of NGC 253 and M82 by OSSE is suggested in order to maximize the chances of gamma-ray line detection from these sources
Energy levels of N14 from N15(He3,α)N14 by Donald D Clayton( file )
1 edition published in 1962 in Undetermined and held by 1 library worldwide
The energy level scheme of N14 in the 4-8 MeV range of excitation has been examined by measuring the alpha-particle spectrum from the reaction N15(He3, α)N14*. States are observed at N14 excitations of 3.95, 4.91, 5.113±0.008, 5.691±0.008, 5.832±0.008, 6.048±0.012, 6.224±0.012, 6.436±0.012, 7.032±0.010, 7.97, and 8.06 MeV. Unobserved are the now doubtful states reported near 6.70, 7.40, and 7.60 MeV in N14. The implications of a possible state near 7.60 on the C12/C13 abundance ratio are discussed and it is concluded that observed isotope abundance ratios are consistent with the finding of this experiment; that is, that such a level does not exist. Angular distributions are presented which show the evidence of different reaction mechanisms to different final states. The reaction N14(He3, α)N13* also produced resolvable alpha-particle groups to states in N13 with excitations of 6.38, 6.91, 7.1 6±0.008, and 7.388±0.008 MeV
Compton Observatory OSSE Studies of Supernovae and Novae ( file )
1 edition published in 1995 in English and held by 1 library worldwide
A primary objective of the Compton Observatory is the direct study of explosive nucleosynthesis in supernovae and classical novae. We have been fortunate in that three rare events have coincided, relatively speaking, with the Compton Observatory launch. Supernova 1987A, roughly a once per century event, was only 4 years old at launch and so the gamma-ray flux from 57Co decay was not much past its peak value. Supernova 1991T, a SN Ia which exploded within a few days of launch, is a once in a decade event. It offers as good a chance as we could reasonably expect to detect the 56Ni and 56Co decays which are supposed to be responsible for the impressive SN Ia display. Nova Cygni 1992, also a once in a decade event, might be our best chance to detect gamma-rays from 22Na, a unique nucleosynthesis byproduct of the explosive hydrogen burning thought to power classical novae
Studies of certain nuclear processes in stars. I. Neutron capture chains in heavy element synthesis. II. A search for excited states in N^(14) pertaining to the synthesis of C^(13) by Donald D Clayton( file )
1 edition published in 1962 in Undetermined and held by 1 library worldwide
Part I. A. An analysis of the abundance distributions resulting from a chain of successive neutron captures is presented in considerable generality. The solutions are applied to the stellar problem of neutron capture at a rate slow compared to beta-decay, the so-called s-process. Theoretically al abundance distributions are correlated with present knowledge of element and isotope abundances in order to draw inferences about the "history” of stellar neutron capture. A semiempirical analysis of isotopic neutron capture cross sections is appended. This work was carried out in conjunction with W. A. Fowler, T. E. Hull, and B. A. Zimmerman. The presentation is in the form of a reprint of an article from the Annals of Physics by the same authors. B. The studies described in Section A have been independently extended in this thesis. A theoretical table of solar abundances is presented for the stable heavy nuclei whose formation is attributable to the operation of the r- and s-processes. The importance of the normalization of these two theories to certain key abundance determinations is emphasized. The table facilitates a comparison of these theories of nucleosynthesis with current observations on the abundances of the elements and their isotopes. Part II. Experimental nuclear studies relevant to astrophysical situations constitute the second part of this thesis research. Alpha particle groups from the reactions N^(15) (He^3, α) N^(14) and N^(14) (He^3, α) N^(13) leading to states in the 7-8 Mev excitation range of the two nitrogen isotopes are reported. States were observed in N^(14) at excitations of 8.06, 7.97, and 7.034 ± .008 Mev and in N^(13) at excitations of 7.388 ± .008 and 7.166 ± .008 Mev. Differential cross sections are evaluated for these reactions at laboratory angles of 90° and 150° and a bombarding energy of 2.76 Mev. No other states in this range of excitation were observed. In particular, a state does not appear near 7.6 Mev excitation in N^(14), indicatin
