Determination of the cluster-decay branching ratio from a near-threshold molecular state in ${}^{10}$Be

W. Jiang, Y. L. Ye, C. J. Lin +27

A puzzle has long existed for the $\alpha$-cluster content in the near-threshold 7.54 MeV state of ${}^{10}$Be. A new measurement was conducted to measure the cluster-decay partial width…
