Study of the level structure of ⁴⁸Ti using the ⁴⁷Ti(n,γ) reaction

The capture γ-ray spectrum resulting from thermal-neutron capture in ⁴⁷Ti has been measured using a 30-cm³ Ge(Li) detector and angular-correlation measurements carried out using NaI(Tl) detectors. Some 28 γ lines corresponding to transitions between levels of ⁴⁸Ti were observed, and the neutron separation energy of Ti48 was determined to be 11.630±0.008 MeV. The following assignments of spins and parities for some levels were made: 2.422(1⁺, 2⁺, 3⁺), 3.626(2⁺, 4⁺), 3.794(2⁺, 3⁺, 4⁺), and 4.467(2⁺, 3⁺). The results of a comparison between the measured strengths of exciting the Ti48 levels in the (n,γ) and (d,p) reactions are discussed.
