摘要：

Relativistic calculations of the non-mesonic decay of the A particle in nuclear medium are compared with those under the non-relativistic and static approximations. Near the normal density of nuclear medium, the relativistic results give considerably larger decay rates and neutron/proton ratios than non-relativistic ones.
