Abstract
A particle-gamma angular correlation coincidence technique enabling the measurement of 0° coincidences was used to study levels in 15O at 5.24 MeV (Jπ = 5 2+), 6.18 MeV (Jπ = 3 2-), 6.79 MeV (Jπ = 3 2+) and 6.86 MeV (Jπ = 5 2+). The multipole mixing ratios of the de-excitation γ-rays were determined as the following: x(5.24→ 0) = +0.08±0.08 an E3/M2 mixture; x(6.86 → 5.24) = +0.04±0.03, an E2/M1 mixture; x(6.79 → 0) = -0.02±0.02, an M2/E1 mixture and x(6.18 → 0) = -0.121 ±0.008 an E2/M1 mixture. The latter value is to be compared with x((E2/M1) = +0.13 ±0.02 for the mirror 6.323 MeV transition in 15N indicating |x(15O)| ≦ |x(15N)| contrary to previous findings (10). The results obtained, together with those corresponding to mirror transitions in 15N are compared with recent IPM and core polarization theoretical investigations.
