Gamma-ray spectroscopy studies ofTi52

Abstract
Nuclear properties of the excited states of Ti52 were measured using the Ti50(t,pγ) reaction at a bombarding energy of Et=2.9 MeV. Angular correlations of γ rays were obtained using an array of five NaI(Tl) counters in time coincidence with an annular particle detector positioned near 180°. Unique spin assignments for some of the excited states were obtained in addition to multipole-mixing-ratio and branching-ratio information. Nuclear lifetimes were measured using the Doppler-shift-attenuation method. Some of the measured excitation energies, spins, and mean lifetimes [Ex (keV), J, and τ (psec)], respectively, are as follows: (1047.1±0.3,2,4.82.1+8.0); (2259.4±0.6,2,0.050.02+0.03); (2427.9 ± 1.5, 2, ≤0.1); and (3582.5 ± 2.0, ≥1, ≤0.09).
