Development of neutron-rich radioactive beams at the Holifield Radioactive Ion Beam Facility has stimulated experimental and theoretical activity in heavy Sn and Te isotopes. Recently, the g factor of the first 2 + state in 132 Te has been measured. We report here new shell-model calculation of magnetic moments for selected Sn and Te isotopes. The residual interaction is based on the CD-Bonn renormalized G matrix. Single-particle spin and orbital effective g factors are evaluated microscopically including core polarization and meson exchange currents effects.

A full two-body shell-model calculation has been used to estimate the pion-exchange contribution to the parity-violating u decay of the 0+, T = 1 state of 6Li. For a neutral-current-induced weak pion amplitude equal to the "best" value given by Desplanques, Donoghue, and Holstein, the o. width is 1.3&10 eV.There is no contribution in lowest order from the intrinsic parity impurity in the u particle, but there is a small contribution from the deuteron.NUCLEAR STRUCTURE 6Li.
