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