Observation of a $μs$ isomer in $${134\atop{49}}$$In$$_{85}$$: Proton-neutron coupling "southeast" of $${132\atop{50}}$$Sn$$_{82}$$
Abstract
In this paper, we report on the observation of a microsecond isomeric state in the single-proton-hole, three-neutron-particle nucleus 134In. The nuclei of interest were produced by in-flight fission of a 238U beam at the Radioactive Isotope Beam Factory at RIKEN. The isomer depopulates through a γ ray of energy 56.7(1) keV and with a half-life of $$T_{1/2}$$ = 3.5 (4) $μs$. Based on the comparison with shell-model calculations, we interpret the isomer as the $I^π$ = 5-member of the $$π0g{-1\atop{9/2}}Ⓧv1f{3\atop{7/2}}$$ multiplet, decaying to the $I^π$ = 7- ground state with a reduced-transition probability of $B (E$2; 5- $$\rightarrow$$ 7- = 0.53 (6) W. u. Observation of this isomer, and lack of evidence in the current work for a $I^π$ = 5- isomer decay in 132In, provides a benchmark of the proton-neutron interaction in the region of the nuclear chart “southeast” of 132Sn, where experimental information on excited states is sparse.
