Theoretical data

Theoretical PSF data recommended by the IAEA CRP on Reference Database for Photon Strength Functions are also available for downloading. These theoretical PSFs were validated according to the CRP prescription [1].

Two global models have been used to perform global calculations of E1 and M1 PSFs for all nuclides across the nuclear chart: the D1M-QRPA and SMLO. Details about the models and calculations are available in [1], [2], and [3].

The files contain PSFs in units of [MeV-3] at various excitation energies U (QRPA files) or temperature T (SMLO files) so that they can be used for de-excitation processes. Note that for photoabsorption, U=0 or T=0, while for de-excitation the user needs to use the relation: U=aT² with a=A/10.

Other models

Theoretical PSF data generated by the triple Lorentzian model (TLO) [4] are now also available for dowloading. The folder contains the source files for generating the PSF data as well as the data files themselves. These PSFs have not been validated according to the CRP prescription [1].
