E1 Strength Functions

(Last update: 18/12/2025)

The present E1 strength functions are obtained by a large-scale calculation within the covariant-EDF framework. It is referred to as RQFAMz. The ground state is calculated as a RHB state using the covariant functional DD-PC1 [1] for the particle-hole channel and a separable pairing force. The E1-strength is then built via an axially-deformed FAM-QRPA approach [2]. In order to obtain a dataset reproducing at the same time the low- and high-energy parts of the experimental E1 strength, a folding procedure is applied. Details can be found in Ref [3].

The files below are in TALYS format, i.e. the E1 strength function is expressed in mb/MeV. It can be transformed in MeV^-3 by multiplying it by the constant factor of 8.67373E-08.
