Abstract
The 186W(t, α) 185Ta reaction has been studied using 17 MeV tritons with a polarization of ≈ 0.78 from the Los Alamos tandem Van de Graaff accelerator facility. The reaction products were momentum analyzed with a Q3D magnetic spectrometer and detected with a helical-cathode position-sensitive proportional counter. No nuclear structure information is available in the literature for the neutron rich 185Ta isotope. A comparison of the measured angular distributions for the (t, α) reaction with DWBA predictions permitted spin and parity assignments for some levels. Rotational bands have been assigned for the 7/2+[404], 9/2-[514], 1/2+[411], and 7/2-[523] orbitals, and a tentative suggestion is given for the location of the 3/2+[411] orbital.
