We have performed shell-model calculations of the half-lives andneutron-branching probabilities of the r-process waiting point nuclei at themagic neutron number N=82. These new calculations use a larger model space thanprevious shell model studies and an improved residual interaction which isadjusted to recent spectroscopic data around A=130. Our shell-model resultsgive a good account of all experimentally known half-lives and $Q_\beta$-valuesfor the N=82 r-process waiting point nuclei. Our half-life predictions for theN=82 nuclei with Z=42--46 agree well with recent estimates based in theenergy-density functional method.
