Probing the neutron-proton asymmetry dependence of the nuclear source temperature with light charged particles

NUCLEAR REACTIONS ¹¹²Sn(⁶⁴Zn, X), (⁶⁴Ni, X), E=40 MeV/nucleon; ¹²⁴Sn, ^58,64Ni, ¹⁹⁷Au, ²³²Th(⁷⁰Zn, X), (⁶⁴Ni, X), E=40 MeV/nucleon; measured differential σ(θ) for light charged particles: neutrons, protons, deuterons, tritons, ³He and α particles in coincidence with intermediate mass fragments (IMFs) at different lab angle, and apparent temperatures using silicon E-ΔE detector telescope for the detection of IMFs, CsI detectors for light charged particle, and DEMON array for neutrons at the K-500 superconducting cyclotron of Texas A and M University; deduced dependence of nuclear temperature on source neutron-to-proton asymmetry. Comparison with statistical multifragmentation model (SMM), and with antisymmetrized molecular dynamics (AMD-Gemini) calculations.
