抄録: | We investigate double Lambda hyperfragment formation from the statistical decay of double Lambda compound nuclei produced in the Xi(-) absorption at rest in the light nuclei C-12, N-14, and O-16. We examine the target and the Lambda Lambda bond energy dependence of the double Lambda hyperfragment formation probabilities, especially of those double hypernuclei observed in experiments. For the 12C (N-14) target, the formation probabilities of 6 He and 10 Be (B-13(Lambda Lambda)) are found to be reasonably large as they are observed in the KEK-E373 (KEK-E176) experiment. By comparison, for the O-16 target, the formation probability of Be-11(Lambda Lambda) is calculated to be small with Delta B-Lambda Lambda consistent with the Nagara event. We also evaluate the formation probability of H-5(Lambda Lambda) from a Xi(-)-He-6 bound state, H-7(Xi). |
