COMPUTATION OF CORRELATION CHARACTERISTICS OF NUCLEAR-REACTIONS INDUCED BY SEMIHEAVY IONS

The present paper suggests a consistent approach to the calculation of different characteristics of nuclear reactions with the production of high-lying quasistationary states of nuclei induced by light and semi-heavy ions with an incident energy up to 10 MeV/nucleon. To investigate this subject it is expedient to analyze the angular correlations of nuclear reaction products. The approach is based on some basic theoretical statements, namely, the general theory of angular correlations in terms of the density matrix and its spin-tensors, two supplementary nuclear reaction models - direct and statistical reaction models - on some methods of computation of quasistationary state characteristics such as the cluster wave functions, width, spectroscopic factors, and, the experimentally observable quantities - differential cross-sections, spin-tensors of the density matrix of the final nuclear state, particle-particle and particle-gamma-quantum angular correlation functions and populations of magnetic sublevels of the final nucleus. The approach has been implemented as a package of FORTRAN programs, applied to the analysis of concrete nuclear reactions.
