Abstract
Excitation functions for the Mo96(p,xn)Tc97x reactions have been measured for proton bombarding energies from 10-80 MeV. These experimental results have been compared to excitation functions calculated using the most recent version of intranuclear cascade model, that known as VPOT, as well as the older STEP. The two models are compared, particularly with reference to improvements in the newer, more sophisticated VPOT. This model provides substantially better agreement with experiment than STEP, although it is also found to introduce new problems.
