Description
The high spin states of 143Sm have been studied by in-beam γ-spectroscopy following the reaction 130Te(20Ne,7n)143Sm at Elab=137 MeV, using a Clover detector array. More than 50 new gamma transitions have been placed above the previously known Jπ=23/2-, 30 ms isomer at 2795 keV. The level scheme of 143Sm has been extended up to 12 MeV and spin-parity assignments have been made to most of the newly proposed level. Theoretical calculation with the relativistic mean field approach using blocked BCS method, has been performed. A sequence of levels connected by M1 transitions have been observed at an excitation energy ∼8.6 MeV. The sequence appears to be a magnetic rotational band from systematics
