Abstract
An effective residual interaction
between particles and holes for shell model calculations
around
208Pb, derived from the interaction between free nucleons,
is compared with the
measured properties of proton-hole neutron states in
208Tl and the interaction between
proton holes is adjusted to newly measured level energies in
206Hg. These interaction
elements are particularly relevant
for neutron-rich nuclei. The adjustment of two mixing elements reproduces the known
-decay data in
208Tl.
