Preequilibrium (p,p’) spectra for nuclei around neutron number 50

Preequilibrium (p,p’) measurements and calculations forZr90and neighboring nuclei for incident energies up to 200 MeV

“…Our 6ndings regarding the mass dependence are different from those of Watanabe et al [15] for the same reactions studied at an incident energy of 12 to 18 MeV.…”

Toward a global exciton model: the equilibrium component

“…Other groups (e.g. [12,13]) have noted the difficulty in reproducing the proton evaporation intensities in this mass region and have resorted to minor parameter adjustments on a reaction by reaction basis in order to resolve the problem. Such an approach is inappropriate when seeking a global set of model input.…”

Inclusive spectra of(p,xp)and(p,xd)reactions onDuisebayev1, Ismailov2, Boztosun3 2003Phys. Rev. C

“…There are also the experimental (p,xp) spectra for 98 Mo at 12, 14 and 16 MeV [2,3] and for 90 Zr, 54,56 Fe and 93 Nb at 26 MeV [4] from the Kyushu group. In the first case, the target was the self-supporting metallic foil 98 Mo, with a thickness of 450 µg/cm 2 .…”

“…In order to overcome this problem and to cover the soft part of the spectra, we have used a 50 micron ∆E-detector, therefore, the energy range is started from 2.5 MeV for our measurements. Secondly, the protons in the energy region of 30 MeV have not been studied in detail [1,2,3,4] and extending the experiment in this direction allows us to view the mechanisms of the reaction and the level of energy-dependence in detail and to use these observations for adequate analysis within the framework of the FKK theory. Undoubtedly, the extraction of experimental information on channels of reactions with the emission of complex particles (deuteron, tritium, 3 He and 4 He) remains interesting.…”
