Excited levels in 141Xe, populated in spontaneous fission of 248Cm, were studied by means of prompt γ-ray spectroscopy, using the EUROGAMM2 array. Level scheme of 141Xe obtained in this work shows patterns characteristic of simplex symmetry with s = +i and s = −i bands present but low value of D 0 moment indicates that octupole correlations in Xe isotopes are systematically lower than in Ba nuclei.
