     由于在相同的激发能下,蒸发道的相对截面比与复合核的角动量有很强的依赖关系,应用统计蒸发程序(CASCADE),从二中子和三中子蒸发道的截面中提取不同能量下的复合核平均角动量和熔合截面。

     New calculation for isotopic distribution are carried out within the framework of nucleon transport theory with the statistical evaporation model in the intemediatie energy heavy ion collision. Some dynamical effects on isotopic distribution are discussed. The isotopic distributions of projectile fragmentaion (Z from 6 to 10) in 40 Ar+ 181 Ta reaction are well reproduced.

  statistical evaporation
The analysis of the fragmentation products reveals that the absorption of a photon is followed by statistical evaporation of neutrals with a mean energy loss of 0.28±0.05 eV per evaporated monomer in the large cluster limit.
      
Evaporation residue cross-sections are calculated in a dynamical description of nuclear fission in the framework of the Langevin equation coupled with statistical evaporation of light particles.
      
An explanation of proton andα yields cannot be given by statistical evaporation, but requires the assumption of a preequilibrium mechanism dominating for projectile energies in excess of 20 MeV.
      
Statistical evaporation processes from primary fragments cannot explain all the observed structures.
      
It is evident that such results are not clearly interpreted in the statistical evaporation theory and that level densities of the residual nucleus cannot be derived.

  statistical emission
The γ-ray spectra obtained in coincidence with 8Be and 12C * (0+2) emission have been studied relative to the statistical emission of two or three α-particles.
      
At most half of the coincident events can be attributed to statistical emission ofα-particles from the fully accelerated projectile-like fragments.
      
This statistical emission of only a few neutrons is controlled by very strong y-ray competition: theγ-entry line is found not to be parallel to the yrast line.
      
Photon energy spectra measured in the energy range from 2 to 20 MeV in coincidence with ejectiles coming from deep inelastic reactions, are consistent with statistical emission from the reaction products.
      
These data are in good agreement with the predictions of a simple moving source model, indicating statistical emission of the fragments from a nearly equilibrated compound nucleus.

The angular distributions of fission fragments and the excitation functions have been measured for the ~(12)C+~(209)Bi and ~(14)N+Pb reactions with a gold surface barrier silicon detector and mica nuclear track detectors. The measured fission excitation functions are found to be in good agreement with those calculated by the statistical evaporation model. The angular-momentum dependent fission barrier is also discussed.

在45—96MeV~(16)O和~(65)Cu反应中,用放射化学技术测量了反应余核的激发函数、角分布和微分射程分布。将实验数据和基于复合核统计蒸发模型的Monte-Carlo模拟计算进行了比较,指出重余核来自全熔合形成的复合核的衰变。提取了该系统的全熔合截面,得到的激发函数与理论计算结果相符合。非完全熔合或大质量转移是生成质量数接近靶质量余核的主要生成机制。
