概要

• 論文の詳細を見る

• Formation mechanisms of single, twin and double hypernuclei from Ξ^- absorption at rest on ^<12>C are investigated with a refined microscopic transport model that incorporates the recently developd quantal Langevin treatment into antisymmetrized molecular dynamics. With a choice of the fluctuation strength that describes dynamical fragmentation processes in the p+^<12>C reaction at 45 MeV quite well, the quantum fluctuations suppress the formation probability of double hyperfragments to around 10%, which is comparable to the experimental data, and the dynamical formation of twin hyperfragment can be described qualitatively.
