Abstract
Excited levels in 133Sn and 134Sb, populated in spontaneous fission of 248Cm, were studied by means of prompt-$\gamma$ spectroscopy, using the EUROGAM 2 multidetector array. The neutron i13/2 single-particle energy has been determined for the first time in the 132Sn region. The energy of the h9/2 neutron level, proposed previously, has been confirmed.
