Abstract
The widely used low-order Brueckner (LOB) scheme for calculating the bindin g energy of the Lambda hyperon in nuclear matter, B-Lambda, is discussed. T wo corrections to B-Lambda are considered: the rearrangement energy and the effect of replacing the LOB spectrum of the single particle Lambda energie s in the intermediate states of the reaction matrix equation by a continuou s spectrum. It is shown that the two corrections approximately cancel.
