IAEA0954 HFTT.

1. NAME OR DESIGNATION OF PROGRAM:  HFTT.

3. DESCRIPTION OF PROGRAM OR FUNCTION

HFTT calculates nuclear reaction cross sections for target nuclei with mass number A GE 40.  The code can predict the nuclear reaction cross sections induced by  proton, neutron and deuteron in the energy range above a few tens of MeV. The output data are limited in the outgoing channels to proton  and neutron at present. Further work will also include some other outgoing channels.

4. METHOD OF SOLUTION

The code HFTT employs a combination of the compound nuclear evaporation model and pre-equilibrium exciton model. The description of pre-equilibrium emission of a composite system is based on the formula of Cline. The intranuclear transition rate of Oblozinsky et al. and Kalbach-Cline's expression for the matrix element of the residual interaction are used in the code. The normalization constant of the matrix element is adjustable as an input parameter. The first and second emission particles considered  in the program are n, p, t, 3He, d, 4He and gamma ray. The third emission particles considered are p, n and gamma ray. We chose the initial exciton configuration of n0=3(2p,1h) for nucleon induced nuclear reactions and of n0=3(2p,1h) or n0=4(3p,1h) for deuteron induced reactions. The level densities are calculated by the formula of Gilbert-Cameron. The optical model is used to evaluate the inverse cross sections of the nuclear reactions. In order to reduce  the number of adjustable input parameters, the optical parameters recommended by Becchetti, Perey and Mefadden , which are universal suitable in some range, are used in the program.
