Abstract

The high-spin structure of Sm139 has been investigated with the Pd110(34S,5n) reaction at a beam energy of 159 MeV at the Stony Brook Tandem/Superconducting LINAC facility. The TESSA3 spectrometer array was used to collect - coincidence data from which an extended decoupled band structure has been found. It is proposed that this band is based on the i13/2 (=1/2) neutron intruder orbital. The decay pattern, enhanced dynamic moments of inertia, and aligned spins are consistent with the i13/2 bands in neighboring odd-neutron nuclides. Total Routhian surface and cranked shell model calculations reproduce qualitative features of these nuclides, further supporting the proposed interpretation.
