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.

Solution method:
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:
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.
