Abstract
We discuss the nonmesonic decay of deformed p-shell hypernuclei. The Nilsso n model with angular momentum projection is employed in order to take into account the deformation effects. The nonmesonic decay rate and the intrinsi c Lambda asymmetry parameter decrease as a function of the deformation para meter, while the ratio of the neutron- to proton-induced decay rates increa ses. We find that the deformation effects change these observables by about 10% for Be-9(Lambda) from the spherical limit.
