An improved code for the calculation of astrophysical reaction rates in the
statistical model is presented. It includes the possibility to study isospin
effects. Such effects heavily affect capture rates involving self-conjugate
nuclei and may also be found in reactions on other intermediate and heavy
targets.Comment: 5 pages LaTeX, uses iopconf.sty, to appear in the proceedings of the
