摘要
介绍了ALICE程序的功能及其使用方法。该程序给出的熔合蒸发激发函数是可信的,而且可用简化方法来完成,但对重离子所引起的反应,只能使用S-波近似公式,对于预言截面来说,采用能级密度参数a=A/12MeV^(-1)较为合适;对熔合裂变截面,通过适当调整刻度参数B_f,可以得到可靠的计算值。该程序也可以给出较满意的包括平衡前发射的粒子能谱。
The functions of the ALICE code and the method of its usage have been introduced. The fusion evaporation exitation functions given by using the ALICE code are reliable and can be accomplished by using the simplifying method, but by using s-wave approximation formula only for reactions induced by heavy ions. The adopted level density parameter α=A/12 MeV^(-1) is suitable for cross section prediction. Dependable fusion fission sections can be obtained by means of regulating scaling parameter B_f properly. The calculated energy spectra of particles emitted by precompound decay are also satisfactory.
