摘要
在２５ＭｅＶ／ｕ４０Ａｒ＋１９７Ａｕ反应中，对两粒子小相对动量的关联进行了测量，由Ｐ－ｔ、α－α关联函数提取出４Ｈｅ、８Ｂｅ的相对态布居．在对影响８Ｂｅ态布居的跟随衰变作了仔细修正后得到的温度为３．５±０．８１．３ＭｅＶ；对４Ｈｅｇ．ｓ．引入３０％跟随衰变产额修正后温度为３．６±０．４ＭｅＶ．
Two particle correlations at small relative momenta have been measured for (40)￣Ar induced reactions on (197)￣Au at E/A=25MeV. The relative populations of states of 4￣He and 8￣Be were extracted from p-t and α-α correlation functions, respectively.The temperature of MeV was obtained from relative populations of 8￣Be 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 4￣He ground state.
