Recent advances in theory of nuclear structure open the way to the use of microscopic models of nuclei for evaluated data. These models are able to target within a single framework a large set of nuclei and predict coherently their structure properties. In particular, gamma-ray strength functions constitute a key ingredient of Hauser-Feshbach’s statistical model for the determination of the neutron capture (emission) cross section given that this physical process is in direct competition with the emission of a photon. In this talk we will show some applications of Quasi Random Phase Approximation (QRPA) method with "ab initio" interactions for the determination of strength functions, and discuss the limitations to overcome in the coming years.
