γ-ray and conversion-electron spectroscopy of the high-spin isomer in ¹⁴⁵Sm

RADIOACTIVITY ¹⁴⁵Sm(IT)[from ¹²⁴Sn(²⁶Mg, 5n), E=110, 115 MeV, followed by separation of evaporation residues by the SOLITAIRE separator and implantation in a catcher tape at the focal point of the Solenogam array]; measured Eγ, Iγ, E(ce), I(ce), γγ- and γ(ce)-coin, half-lives of isomers by γ(t) and γγ(t) at the at the Australian National University Heavy-Ion Accelerator Facility. ¹⁴⁵Sm; deduced high-spin levels, J, π, conversion coefficients, multipolarities, B(E1), B(M1), B(E2), B(M2), B(E3), configurations. Comparisons with shell-model calculations using the KSHELL code. Systematics of energies of the high-spin isomers in N=83, odd-A isotones of ¹⁴³Nd, ¹⁴⁵Sm, ¹⁴⁷Gd, ¹⁴⁹Dy and ¹⁵¹Er.

NUCLEAR STRUCTURE ¹⁴⁵Sm; calculated high-spin levels, J, π, amplitudes of major configurations using shell model and KSHELL code. Comparison with experimental data.
