Relative Population of State and Extraction of Emission Temperature in 25MeV/u 40Ar+197Au

  •  Institute of Modern Physics, Academia Sinica, Lanzhou, 730000

  • 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.
