Abstract：
Two particle correlations at small relative momenta have been measured for ⁴⁰Ar induced reactions on ¹⁹⁷Au at E/A=25MeV. The relative populations of states of ⁴He and ⁸Be were extracted from p-t and α-α correlation functions, respectively.The temperature of MeV was obtained from relative populations of ⁸Be states by correcting sequential decay carefully, and the temperature of T=3.6±0.4MeV was deduced by modifying with 30 percent of sequential decay on ⁴He ground state.
