Low-energy behavior of E2 strength functions

Electric quadrupole strength functions have been deduced from averages of a large number of E2 transition strengths calculated within the shell model for the nuclides 94Mo and 95Mo. These strength functions are compared with phenomenological approximations as provided by the Reference Input Parameter Library (RIPL) for calculations of reaction rates on the basis of the statistical model. The low-energy behavior of the calculated strength functions differs from the one of the phenomenological E2 strength functions and may be used to improve the input for calculations of reaction rates.
