Selective decay from a candidate of the σ -bond linear-chain state in 14C
Abstract
A cluster-transfer experiment 9Be(9Be,*14C→α +10Be)4He was carried out using an incident beam energy of 45 MeV. This reaction channel has a large Q value that favors populating the high-lying states in 14C and separating various reaction channels. A number of resonant states are reconstructed from the forward-emitting 10Be+α fragments with respect to three sets of well-discriminated final states in 10Be, most of which agree with the previous observations. A state at 22.5(1) MeV in 14C is found to decay predominantly into the states around 6 MeV in 10Be daughter nucleus, in line with the unique property of the predicted band head of the σ -bond linear-chain molecular states. A new state at 23.5(1) MeV is identified which decays strongly into the first excited state of 10Be.
