Program complex for calculating the two-particle reaction cross sections

General structure of the REAK-AB program complex intended for computerized calculation of two-particle nuclear reactions in the energy range up to 100 MeV is described. Basis REAK-AB complex program for calculation of binary reactions by optical (ROM-78), statistical (SMT-80) models, method of distorted waves (VAR-82) and strong bond of channels (SSA-83) are written in the FORTRAN-4 language for BEhSM-6 and ES-1060 type computers. Different angular distributions of two-particle nuclear reactions such as differential cross sections, parameters of vector and sections and strength functions are calculated by these programs. Analysis of data by reactions with polarized targets and targets in the initial state is presupposed, and there is a possibility of automatic search for phenomenological parameters of model by different experimental data in a wide kinematic range. Calculations conducted on the base of basic program complex have revealed that the realized structure is easily modernized and expanded, the system can be used as reliable instrument in fundamental researches
