“…This shows the dominating contribution of fission at these energies. Following Biswas and Porile [4], several authors have used this new assumption of a collective model of proton-target interaction to try to explain, first some deep spallation characteristics [5,7,8], then light-fragment production [3,9,29]. We note that the fission contribution is smaller for 81Kr than for 8~ As already noted in a previous publication [8], the neutron-deficient characteristics of 81Kr are more pronounced than those of 8~ This is due to the fact that 81Kr is protected towards fi-isobars, which is not the case for 8~ For 85Kr and 86Kr, the ratios <P)exp/(P)fis vary little with incident energy, indicating that even at 2.5 and 24 GeV, fission remains the principal mechanism responsible for the formation of these neutronexcess isotopes.…”

Cross sections and thick-target recoil properties of several Kr and Xe isotopes formed in the interaction of 197Au with 0.15-24 GeV protons have been determined in order to study their variations with mass product and incident energy. Noble gas isotopic composition and concentration have been obtained by using high sensitivity mass-spectrometry. The measurement of the experimental range, 2W(F+B), and of the forward-tobackward ratio, F/B, permits (with the help of a mathematical formalism based on the two-step model) the determination of some characteristics of nuclear reactions. The results are discussed in terms of fission and spallation mechanisms.

A K-matrix analysis of the ID,, 'F, and 'P,-'F2 partial waves based upon the recent phase-shift analysis by the present author is performed. The analysis provides strong evidence for the existence of the resonance pole in each of these partial waves (two pales in the 'F, wave). Location of the poles relative to the N A cut gives a strong indication that the diproton resonances arise as the unitary reflection of the 'bound' state in the 'S, wave, of the virtual state in the 'P2 wave and of the resonance in the ' P, wave of the NA system. Comparison of the phases of the NA-NA partial amplitudes following from our K-matrix analysis with those ablained in recent partial wave analysis of the pp+ N A reaction shows that the results of the latter cannot sene as a refutation of the existence of diproton resonances. The discrepancies between our results and the latest of the Blacksburg group analysis are discussed in some detail.
