概要

• 論文の詳細を見る

• A new concept of "atom-nucleus hybrid state" is proposed to explain the second ^9_ΣBe peak observed in the (K-,π-) reaction at CERN. The explanation is based on coupling among the isotriplet states of ^8Be*(16.63 MeV) with corresponding isotriplet of Σ particles. The Coulomb interaction between ^8Be and Σ- prepares a shallow atomic bound state with a narrow conversion width. The coupling of strong interaction between the two states (^8B+Σ^-) and (^8Be*+Σ^0) pushes down the energy of resonance state and it is expected to reproduce the correct energy position and level width of the second peak of the observed ^9_ΣBe hypernuclear spectrum.
