Pionic decay of Lambda Hypernuclei in a Continuum Shell Model
Abstract
We evaluate pionic decay widths of Lambda hypernuclei using a shell model for, both the nuclear bound and the continuum nucleon wave functions in the final state, and distorted waves for the outgoing pion. An excellent agreement with the recent KEK measurement of π--decay widths of 12 and 28 is found. Besides, results for 56 are consistent with the existing upper bound.
