Abstract

The role of neutron excess in the nuclear equation of state is important in many systems from the microscopic to the astronomical, and yet the asymmetry energy remains the largest source of uncertainty in the equation of state. We continue our study of the asymmetry dependence of nuclear caloric curve, measuring evaporation of light charged particles from compound nuclei produced Kr + C fusion reactions. The composition and excitation of the compound nuclei are varied by varying the isotope and kinetic energy of the krypton projectile. Temperatures are extracted with kinetic and chemical probes. The more neutron-rich compound nuclei exhibit higher temperatures than the less neutron-rich compound nuclei. We discuss this in light of previous experimental efforts theoretical predictions.
