Between 1984 and 1986, A. J. Sierk developped the BARFIT routine to compute fission barrier, ground state energy, maximum angular momentum and moments of inertia in the framework of the liquid drop model for a large range of nuclei. The routine used fitted value over a wide range of A, Z and L and is still available today from the RIPL-3 website 1. In this paper, I will decribe the re-implementation of the routine in python. This work is motivated by the difficulty to compile 1986's FORTRAN code on modern computers, the advantage of easily deploying python code over a wide range of infrastucture (personnal computers, computing grid, containers, …) and the preservation of A. Sierk's work for future use.
