Abstract

The capture γ-ray spectrum resulting from thermal-neutron capture in 49Ti and 50Ti has been measured using a 30- and a 10-cm3 Ge(Li) detector, and angular-correlation measurements were carried out using NaI(Tl) detectors. Some 16 γ lines corresponding to transitions between levels of 50Ti, and 9 γ lines corresponding to transitions between levels of 51Ti were observed. The neutron separation energies of 50Ti and 51Ti were determined to be 10.938 ± 0.008 and 6.377 ± 0.007 MeV, respectively. The following assignments of spins for some levels (in MeV) of Ti50 and the first excited level of Ti51 were made: 1.555 (2+), 2.675 (4+), 4.151 [2+, 3+, 4+, (5+)], 4.178 (2+, 3+, 4+), 4.887 [2+, 3+, 4+, (5+)], 5.195 (2+, 3+, 4+), 5.382 [2+, 3+, 4+, (5+)], 5.948 [3+, 4+, (5+)] for 50Ti and 1.164 (1/2-) for 51Ti. There are some indications that only the 3- capture-state spin contributes to the population of the low-lying levels in 50Ti. The results of a comparison between the measured strengths of exciting the 50Ti levels in the (n,γ) and (d,p) reactions are discussed.
