Abstract
Excited levels in 133Sn and 134Sb, populated in spontaneous
fission of 248Cm, were studied by means of prompt-
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.
