Abstract：
Two-particle correlations at small relative momenta have been measured for ⁴⁰Ar induced reactions on ⁹⁷Au at E/A=25 MeV. The relative populations of states of ⁴He and ⁸Be were extracted from p-t and α-α correlation functions, respectively. The temperature of T=3.5±_0.8^1.3 MeV was obtained from relative populations of ⁸Be states by correcting sequential decay carefully, and the temperature of T=3.6±0.4 MeV was deduced by modifying the sequential decay yield with 30% on ⁴He_g.s. ground state.
