The high spin states of {sup 143}Sm have been studied by in-beam {gamma}-spectroscopy following the reaction {sup 130}Te({sup 20}Ne,7n){sup 143}Sm at E{sub lab}=137 MeV, using a Clover detector array. More than 50 new gamma transitions have been placed above the previously known J{sup {pi}}=23/2{sup -}, 30 ms isomer at 2795 keV. The level scheme of {sup 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 {approx}8.6 MeV. The sequence appears to be a magnetic rotational band from systematics.
