Abstract

The reaction F19(t, α)O18 has been used to study the E0 π decays of the O18(3.63 MeV, 0+) and O18(5.33 MeV, 0+) states to the ground state. The E0 branching ratios ΓπΓ were measured to be, respectively, (3.0±0.6) × 103 and ≤ 2.3 × 103. When these values are combined with the available lifetimes of these states, E0 matrix elements Mπ=(6.0±0.7) fm2 [O18(3.63 MeV)] and ≤ 4.5 fm2 [O18(5.33 MeV)] are obtained. The properties of these states are compared to the theoretical predictions.

NUCLEAR REACTIONS F19(t, α), E=2.2 MeV; O18 measured E0 branching ratios. Deduced E0 matrix elements.
