Abstract:

Formation process of double-Λ hypernuclei is investigated on the basis of the idea of a double-Λ compound nucleus formed in Ξ absorption. The behavior of a hyperon in nuclear medium is studied by calculating the elastic/conversion widths and the mean free path, and the probabilities of single-Λ and double-Λ sticking after the ΞN →ΛΛ conversion are discussed. The decay probabilities from a double-Λ compound nucleus to various fragments are evaluated in a statistical treatment.
