Abstract

Particle-gamma angular correlations and lifetime measurements (delayed coincidences and DSAM) have been performed in the 26Mg(t, α)25Na reaction. The results for Jπ (and τm) are 3 2+ or 5 2+ (7.4±0.4 ns), 1 2+ (2.3-0.8+2.0 ps), 3 2+ (<25 fs), 7 2+ (200±140 fs) and 3 2 or 7 2 for the levels at 90, 1069, 2202, 2417 and 2788 keV respectively. Branching and mixing ratios have been measured, and strengths of the transitions calculated. Evidence for configuration mixing is given. The results are compared with shell-model calculations.
