Abstract

The Λ\Lambda separation energy for Λ\Lambda-hypernuclei, denoted BΛB_\Lambda, measured in 1967, 1968, and 1973 are recalibrated using the current best mass estimates for particles and nuclei. The recalibrated BΛB_\Lambda are systematically larger (except in the case of Λ6^6_\LambdaHe) than the original published values by about 100 keV. The effect of this level of recalibration is very important for light hypernuclei, especially for the hypertriton. The early BΛB_\Lambda values measured in 1967, 1968, and 1973 are widely used in theoretical research, and the new results provide better constraints on the conclusions from such studies.
