本文报道了２５ＭｅＶ／ｕ４０Ａｒ＋１９７Ａｕ反应中粒子－粒子关联函数的实验结果．利用三体弹道模型从关联函数提取了轻粒子发射时间．轻粒子的平均发射时间随粒子能量而变化，从低能时的约３００ｆｍ／ｃ下降至高能时的约１００ｆｍ／ｃ．
This paper reports the experimental results of the particle-particle correlation function in the 25MeV / u40Ar + 197Au reaction. Light particle emission time was extracted from the correlation function by using the three-body ballistic model. The average launch time of light particles varies with particle energy, from about 300 fm / c at low energy to about 100 fm / c at high energy.
