[en] The set of FORTRAN77 functions for partial nuclear level densities was developed. The resulting computer code includes 14 formalisms to calculate partial (particle-hole) nuclear level densities. These quantities are of importance as input for nuclear model calculations of nuclear reaction data. The code was included in the IAEA Reference Input Parameter Library (RIPL Starter File). It was officially released on 15 may 1998 and it is available both on the Web (http://iaeand.iaea.or.at/ripl) or on CD-ROM. The relevant file is avrigeanu.for in the segment Level Densities of the RIPL Starter File. (author)
