Neutron pickup on 93Nb

The reaction 93Nb(3He,α)92Nb has been investigated with a 19.5 MeV 3He beam. Forty-five 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 lsub(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(1gsub(9/2))γ(2dsub(5/2))]sub(Jsup(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 gsub(9/2) pickup strength has been observed in the present experiment and its centroid energy is at 3.11 MeV excitation. (Auth.)
