'Target mass' and 'effective target mass' by M. F Kaplon( Book )

2 editions published in 1964 in English and held by 2 WorldCat member libraries worldwide

The concept of 'Target Mass' and 'Effective Target Mass' is discussed. Evidence is presented which questions the validity of attempting to relate the 'Effective Target Mass' to the concept of a virtual pion surrounding the nucleon. Relations between the 4-momentum transfer, the quantity (E - P cos theta) of the recoil nucleon and the 'Effective Target Mass' are derived which show in conjunction with experimental data that the 'Effective Target Mass' of the order of a pion mass occurs accidentally.

A model for the origin and properties of the cosmic ray rigidity spectrum by M. F Kaplon( Book )

2 editions published in 1966 in English and held by 2 WorldCat member libraries worldwide

A model is proposed to explain a number of features of the differential rigidity spectra of the nuclear component of the primary cosmic radiation. A supernova explosion is assumed to result in the acceleration of nuclei to a pure power law rigidity spectrum and a composition relatively rich in heavy and medium weight nuclei. The supernova remnant into which these particles are injected is characterized as a large scale trapping region resulting from predominantly closed magnetic field lines which partially isolate the region from the surrounding galactic space. This feature of the supernova region is represented by a dipole-like field. Superimposed on this field we assume that magnetic irregularities produce a certain amount of distortion of the field lines in the interior of the source; and irregularities along the periphery of the source lead to local distortions of the field and hence, a mixing of galactic and source field lines in the neighborhood of these irregularities.

The flux of cosmic ray particles with z> or = to 2 over texas( Book )

1 edition published in 1938 in English and held by 1 WorldCat member library worldwide

The fluxes of multiply charged cosmic ray particles have been measured with nuclear emulsions in a high altitude balloon flight. The identification of alpha particles was based on 'blob-gap' measurements while those of elements with Z> or = to 3 on cosmic ray densities. The charge resolution obtained was satisfactory. To calculate the fluxes at the top of the atmosphere an extrapolation procedure, previously introduced in this laboratory, was employed. Two sets of parameters which account for the interactions in the residual atmosphere, differing considerably as far as their influence on the fluxes of light elements is concerned, were used.

The energy dependence of the abundance of lithium, beryllium, and boron in the primary cosmic radiation: observations at fort churchill( Book )

1 edition published in 1964 in English and held by 1 WorldCat member library worldwide

The relative abundance of Lithium, Beryllium, Boron, and the S-group nuclei has been determined at two different energies with the help of a pure nuclear emulsion stack flown from Fort Churchill, Canada (lambda = 70.5) on 4 August, 1962 under a total of 4.7 g/sq. cm of residual atmosphere. The ratio of the L to S nuclei, LS, at the top of the atmosphere between 200-700 Mev/n and> 700 Mev/n was determined as 0.41 = 0.08 and 0.19 = 0.03 respectively. The results of both the absolute flux values of L and S-group nuclei as well as their ratios are in accord with other investigations. Combined with the evidence from the measurements of He3He in the same stack, our results indicate that low energy cosmic ray nuclei have traversed about twice as much hydrogen as high energy particles. The results rule out an accelerating mechanism of the Fermi type but may be explained by a source-trapping mechanism. (Author)

The natuture of the momentum spectrum of secondary shower particles from high energy collisions by H. H Aly( Book )

1 edition published in 1963 in English and held by 1 WorldCat member library worldwide

The nature of the laboratory momentum spectra of the secondary shower particles from high-energy nuclear interactions (E p> 14 GeV) is investigated. By folding the well-established distribution for the transverse momentum, p t, of the secondary shower particles obtained at various primary energies with the differential space angular distributions of shower secondaries, the differential momentum spectrum in the laboratory system is found to be well represented by N(p) dp = N₀ exp. ( - c₁ / p supc²) x 1/p¹(sup a) [1 - c₃ / p (sup c)²] dp. It is shown that a power law representation does not fit the whole range of the momentum spectrum. The spectrum obtained utilizing a constant value for the transverse momentum differs appreciably from the above for momenta less than 1 GeV/c
