nucmass_ibm_shell
¶ An approximation of shell effects in nuclei based on the interacting boson model.
Shell effects from Dieperink09 based on the interacting boson model, with corrections as suggested by Duflo95.
The default shell correction coefficients -1.39, 0.02, 0.03, and 0.075 (all in MeV), respectively.
