The single fermion is assumed to be in a Ih(9/2), 3p(3/2), 2f(5/2) or 3p(1/2) single-particle orbit. The calculated negative high-spin state energy spectra of the odd Er isotope were found to agree quite well with the experimental data. The B(E2) values were also calculated and compared with the experimental data.eninfo:eu-repo/semantics/closedAccessinteracting boson modelinteracting boson fermion modelhigh-spin statesArticle49160652-s2.0-33747081651Q3WOS:000239073100009Q2
