Abstract

The reaction ⁹³Nb(³He, α)⁹²Nb has been investigated with a 19.5 MeV ³He beam. Fortyfive levels of ⁹²Nb were identified up to 4.36 MeV excitation energy. Angular distributions were measured and compared with DWBA calculations. A previously unreported set of states arising from l_n = 4 pickup was observed in the excitation energy range 2.75-3.75 MeV. Fourteen additional lower levels in ⁹²Nb were identified to proceed with l = 4 and l = 2 + 4 neutron pickup, of which eleven were unassigned previously. The sextuplet of levels of the ⁹²Nb ground-state configuration [π(1g_{9 2})v(2d_{5 2})]_j^π = 2⁺ → 7⁺ have angular distributions characteristic of l = 2 neutron pickup. Extracted spectroscopic factors are compared with previous neutron pickup results. The sum-rule analysis shows that most of the g_{9 2}. pickup strength has been observed in the present experiment and its centroid energy is at 3.11 MeV excitation.
