β decay of 133In : γ emission from neutron-unbound states in 133Sn
Abstract
Excited states in 133Sn were investigated through the β decay of 133In at the ISOLDE facility. The ISOLDE Resonance Ionization Laser Ion Source (RILIS) provided isomer-selective ionization for 133In, allowing us to study separately, and in detail, the β-decay branch of 133In Jπ = (9/2+) ground state and its Jπ = (1/2−) isomer. Thanks to the large spin difference of the two β-decaying states of 133In, it is possible to investigate separately the lower and higher spin states in the daughter, 133Sn, and thus to probe independently different single-particle and single-hole levels. We report here new γ transitions observed in the decay of 133In, including those assigned to the deexcitation of the neutron-unbound states.
