Description
The first case of a Bose-Fermi critical point symmetry, E(5/4), representing the coupling of a j=3/2 fermion to an E(5) core, was recently proposed. Since 134Ba has been found to be an empirical manifestation of E(5), we carried out a β-decay experiment to study levels in 135Ba, where the last neutron can occupy the 2d3/2 orbit, as the first test of E(5/4). The comparison shows significant areas of agreement as well as significant discrepancies. Comparison of interacting boson-fermion approximation and shell model calculations with the data are also presented
