High-spin structure and intruder excitations in 36Cl
Abstract
Excited states up to Jπ=11− at 10 296 keV and Jπ=10+ at 10 707 keV have been populated in the odd-odd 36Cl nucleus using the 24Mg(14N, 2p) fusion-evaporation reaction at Elab=31 MeV. Twenty new states and 62 new γ transitions have been identified by employing γ-γ and γ-γ-γ coincidences. Lifetimes have been investigated by the Doppler shift attenuation method. The experimental data have been compared with the results of large-scale shell-model calculations performed using different effective interactions and model spaces allowing particle-hole excitations across the N=Z=20 shell gap.
