Nature of problem:
The program SATTNT calculates the form factor for two-nucleon transfer reactions. The approach adopted in this program is the exact-finite- range microscopic theory. The created form factor is to be used in for instance the MARS-1 program to calculate the DWBA cross sections, catalogue number ABPA CPC 8(1974)349.
The radial part of the wave functions of the bound nucleons are expanded in terms of oscillator functions and then Moshinsky transformed by using a program developed by Feng and Tamura (C.P.C. 10(1975)87). To evaluate the kernels of EFR form factors, one-dimensional integrals are carried out by Gaussian quadrature, introducing a specific technique (C.P.C. 8 (1974)349) so as to minimize the number of quadrature points. Throughout the program interpolation and other techniques are used (as mentioned above) so that an EFR calculation can be performed reasonably quickly.
Restrictions on the size of the calculation come about mostly from the number allowed for the pairs (L1, L2), where L1 and L2 are orbital angular momenta of the center-of-mass motion of the two transferred nucleons, respectively, in the donor and acceptor nuclei. However, only a very small number of pairs actually contribute to the reaction and the storage presently assigned will meet the needs of most practical calculations.
