Measurement of the $\ddot{I}{€}^{-}$ decay width of ${}_{\hat{I}}^5›$He

Abstract

We have precisely measured $\hat{I}›\to p\ddot{I}{€}^{-}$ decay width of \5LHe and demonstrated significantly larger $\hat{I}\pm$ -$\hat{I}›$ overlap than expected from the central repulsion $\hat{I}\pm$-$\hat{I}›$ potential, which is derived from YNG Λ$-nucleon interaction.
