Isobaric analog state energy in deformed nuclei: A toy model / X. Roca-Maza, H. Sagawa, G. Colò. - In: PHYSICAL REVIEW C. - ISSN 2469-9985. - 102:6(2020 Dec). [10.1103/PhysRevC.102.064303]
Abstract:
A formula to evaluate the effects of a general deformation on the Coulomb direct contribution to the energy of the isobaric analog state (IAS) is presented and studied via a simple yet physical model. The toy model gives a reasonable account of microscopic deformed Hartree-Fock-Bogoliubov (HFB) calculations in a test case, and provides a guidance when predicting unknown IAS energies. Thus, deformed HFB calculations, to predict the IAS energies, are performed for several neutron-deficient medium-mass and heavy nuclei which are now planned to be studied experimentally.
