Abstract
In this work, the ground state, quasi beta and quasi gamma band energies of 114,116,118,120Xe isotopes have been investigated by using the both (IBM-1 and IBM-2) versions of interacting boson model (IBM). In calculations, the theoretical energy levels have been obtained by using PHINT and NP-BOS program codes. The presented results are compared with the experimental data in respective tables and figures. At the end, it was seen that the obtained theoretical results are in good agreement with the experimental data.
Highlights
One of the most remarkable simplicities of atomic nuclei is that the thousands of 2-body nucleonic interactions in a nucleus can be reduced to and simulated by a 1-body potential [1]. This is done with the interacting boson model (IBA) [2], which is a useful model to formalize description of symmetry in nuclei
This model (IBA) has a U(6) group structure leading to sub-groups chains denoted by U(5), SU(3) and O(6), which describe vibrational, axially symmetric rotational and γ-soft rotational nuclei. These three symmetries are denoted with a symmetry triangle called Casten triangle
In ref. [15], some of the energy results calculated by interacting boson model (IBM) are compared with the values obtained by pair-truncated shell model (PTSM)
