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-αcorrelation functions, respectively. The temperature of T=3.5± _0.8 ^1.3MeV 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.
