Three beta-decaying states in ¹²⁸In and ¹³⁰In resolved for the first time using Penning-trap techniques

ATOMIC MASSES ^{128,128m,130,130m}In; measured time-of-flight ion cyclotron resonance (TOF-ICR) frequencies for the ground states and two isomers each in ¹²⁸In and ¹²⁸In using the JYFLTRAP Penning trap at the IGISOL facility at the University of Jyvaskyla; deduced mass excesses of three beta-decaying states each in ¹²⁸In and ¹³⁰In, and energies of respective isomers, configurations. Activities of ^128,130In produced as fission products in U(p, F), E=30 MeV at the Ion Guide Isotope Separator On-Line (IGISOL) facility. Comparison with literature values. ¹²⁸Sn, ¹²⁸In, ¹³⁰In; calculated levels, J, π, configurations using shell-model with the effective interaction jj45pna, and compared with experimental data.

RADIOACTIVITY ^128mIn(β^-)[from U(p, F), E=30 MeV at the IGISOL facility]; measured Eγ, Iγ, βγ-coin, half-life of the new (16+) isomer of ¹²⁸In. ¹²⁸Sn; deduced levels, J, π.

COMPILATION ^{130,131,132,133,134}Te, ^{129,130,131,132,133}Sb, ^{128,129,130,131,132}Sn, ^{127,128,129,130,131}In, ^{126,127,128,129,130}Cd; compiled ground and isomeric states using data from the ENSDF and XUNDL databases, together with results for In isomers in the present work.
