Investigation of the C 14 + α molecular configuration in O 18 by means of transfer and sequential decay reaction
A multinucleon transfer and cluster-decay experiment, namely 9Be(13C,18O*→14C+α)α, was performed at a beam energy of 65 MeV. Resonant states in 18O from 7 to 19 MeV, including some newly observed ones, are reconstructed with high resolution, based on the coincident detection of various combinations...

| description | A multinucleon transfer and cluster-decay experiment, namely 9Be(13C,18O*→14C+α)α, was performed at a beam energy of 65 MeV. Resonant states in 18O from 7 to 19 MeV, including some newly observed ones, are reconstructed with high resolution, based on the coincident detection of various combinations of the final fragments. Here, the α-decay branching ratios for 14 states are extracted from both the invariant-mass and the missing-mass measurements. Angular correlation analysis was conducted for the 10.3-MeV (4+) state. The present work supports the existence of the positive-parity rotational band associated with the 14C+α molecular structure in 18O, but the negative-parity band members were not identified. |
