Spectroscopic study of ³⁸K above the 31.67 μs isomer

NUCLEAR REACTIONS ¹²C(²⁸Si, np)³⁸K, E=110 MeV; measured Eγ, Iγ, γγ(θ)(DCO and ADO), γγ(linear polarization) using the INGA array at 15UD Pelletron accelerator of IUAC-New Delhi. ³⁸K; deduced high-spin levels above the 31.67-μs isomer, J, π, multipolarities, mixing ratios. ³⁵Cl; measured γγ(θ)(DCO and ADO ratios) for six γ rays. Comparison with large-basis shell-model calculations using the code OXBASH.

NUCLEAR STRUCTURE ³⁸K; calculated levels, J, π, B(M1), B(E2), B(E3), spectroscopic factors, structure of the wave functions for excited states using large-basis shell-model calculations using the code OXBASH with different particle restrictions in sd- and pf -shell orbitals. Comparison with experimental data.
