Radiochemical study of alpha particle emission in reactions of $sup 202$Hg with 10--86 MeV protons
Excitation functions have been measured for $sup 202$Hg(p,2pxn), x=0--9, reactions induced by protons of energy 10--86 MeV. Reactions having x>1 exhibit two peaks in their excitation functions, the first below the energy calculated for emission of the individual nucleons. This peak is attributed to emission of an $alpha$ particle. A procedure is proposed for decomposing the excitation functions into two components, one arising from $alpha$ particle emission, the second from emission of individual nucleons. From these, the total yield of $alpha$ particles as a function of incident energy is determined, and the excitation energy spectra associated with $alpha$ emission events is deduced. The $alpha$ particle yields are attributed to more than one mechanism; speculations are advanced on a substantial pre-equilibrium evaporation component to the total $alpha$ particle production. (AIP)
