This manuscript deals with the influence of parity-dependent nuclear level densities on astro-physical reaction rates calculated in the Hauser-Feshbach framework. The inclusion of a parity non-equipartition within the compound nucleus in these reactions has not been examined before. We show that our approximative treatment - that accounts for such non-uniformly distributed parities in the compound nucleus - can have an influence on reaction rates. For a more detailed examination we refer to the corresponding paper [1]. Moreover, we shortly discuss the influence of microscopic calculated E1-strength functions on reaction rates and show that for specific nuclei, additional low-lying E1 strength can increase the reaction rate.
