The target-like fragment excitation energy in Ar-40 (9.5 MeV/nucleon) +Tb-1
59 reaction has been obtained by applying a neutron evaporation calculation
to data resulting from coincidence measurements of projectile-like fragmen
ts and neutrons. The comparison between the data and results of statistical
evaporation simulations with different assumptions of the excitation energ
y sharing between the reaction partners confirms an equal temperature hypot
hesis in describing of fragment heating.
