Excited levels in Sn-133 and Sb-134, populated in spontaneous fission of Cm
-248, were studied by means of prompt-gamma spectroscopy, using the EWROGAM
2 multidetector array. The neutron i(13/2) single-particle energy has been
determined for the first time in the Sn-132 region. The energy of the h(9/
2) neutron level, proposed previously, has been confirmed.
