The energy and angular distribution of protons from 14.8 MeV neutron reactions with Al27 and Co59

Abstract

The energy and angular distribution of protons from Al27 and Co59 when bombarded by 14.8 MeV neutrons has been studied by using a triple coincidence and an anticoincidence proton scintillation spectrometer. The observed spectra have been compared to the calculated ones, on the basis of the volume direct interaction and the statistical models. Various level density formulae based on the Fermi gas model of the nucleus have been tried and it has been noted that the level density formulae of Lang-LeCouteur and Newton give the best results. The agreement between the theory and experiment is only qualitative. The behaviour of the nuclear temperature is studied at various angles.
