Research reported in this presentation collaborated with ISOLDE-CERN and the University of Warsaw.

The rapid neutron capture (r-) process final yields are determined by waiting point nuclei where neutron-capture and photo-disintegration are in equilibrium. The decay properties of these nuclei, half-lives and neutron branching ratios determine the path out of these waiting points.

In this work we study the nuclear structure of 133Sn populated in the beta-decay of 133In. Indium 133 was created in induced fission of 238U at the ISOLDE facility CERN. Its delayed gamma and neutron emission was observed at the Isolde Decay Station. Preliminary results of gamma and neutron emission from unbound states in 133Sn will be presented.
