摘要：
The new event of double-LAMBDA-hypernucleus, identified as LAMBDA-LAMBDA-Be-10 or LAMBDA-LAMBDA-B-13, is investigated by using the core + LAMBDA + LAMBDA three-body model. The effective LAMBDA-LAMBDA-interactions are derived from the Nijmegen OBE models on the basis of G-matrix calculations. It is shown that the LAMBDA-LAMBDA-interaction energy given by the experiment can be reproduced reasonably with the G-matrix interactions from the Nijmegen models, if the event is interpreted as LAMBDA-LAMBDA-B-13.
