✦ Synopsis

The excitation energy deposited in the reaction 2°gBi(a,a') at 240 MeV has been determined using the TAMU Neutron Ball. The reconstructed average excitation energies as a function of the beam energy losses show that not all of the missing beam energy is usually deposited as thermal excitation in the target nucleus. Requiring an additional coincidence with a light charged particle or fission fragment leads to selection of a significant higher average excitation energy. This effect is extrapolated to explore results of previous GDR decay measurements in the case of a 2°Spb target.
