“…The nucleus 143 Sm (Z = 62) was studied earlier using the reaction 126 Te( 22 Ne,5n), 128 Te ( 22 Ne,7n), 130 Te( 20 Ne,7n) [15] and also by 142 Nd(α, 3n) [16]. Kowanacki et al [16] performed in-beam experiment using the α beam and two detector coincidence set up and proposed a level scheme of 143 Sm up to spin 29/2h at an excitation energy of 4369 keV.…”

“…Kowanacki et al [16] performed in-beam experiment using the α beam and two detector coincidence set up and proposed a level scheme of 143 Sm up to spin 29/2h at an excitation energy of 4369 keV. In both these experiments [15,16], a 30 ms isomer was observed at 2795 keV, with a spin of 23/2 − . The observed level structure was theoretically interpreted [16] as the coupling of the h 11/2 neutron hole to the doubly even 144 Sm core excitations.…”

The high spin states of 143 Sm have been studied by in-beam γ -spectroscopy following the reaction 130 Te( 20 Ne,7n) 143 Sm at E lab = 137 MeV, using a Clover detector array. More than 50 new gamma transitions have been placed above the previously known J π = 23/2 − , 30 ms isomer at 2795 keV. The level scheme of 143 Sm 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.
