The transitional nucleus 152Eu has been studied using the (n, e), (n, 7), (n .... 7), (n, 77), (d,p), (d, t) and (p, d) reactions. The experiments have been performed at nine different laboratories. A model independent level scheme was established including 95 levels below 510 keV and nearly 900 transitions by combination of low energy transitions and reaction data. More than 20 additional levels result from gamma rays and/or charged particle reactions. The level scheme is interpreted in terms of the Nilsson model indicating that 152Eu is a deformed nucleus. Seven rotational bands and Nilsson configurations are established. An additional 27 rotational bands are tentatively or speculatively assugned. Gallagher-Moszkowski splittings are discussed. The neutron binding energy was determined as 6305.2 __ 0.5 keV. The energy of the 9.3h0-isomer is 45.599keV. The lifetimes of four levels were measured.Nuclear Reactions 15tEu(n, 7), E, =thermal and resonance; measured E.~, I~,E .....

“…Since the best (d, t) run was at 95 ~ the 95 ~ results were used and the ~bz(90 ~ of Reference 1 were corrected for the change in angle according to estimates taken from the curves of Elbek and Tjom [15] for the reaction 166Er(d, t)165Er at 12 MeV. The corrections, for /=0 through 6 respectively, were -4 %, -3 %, 0 %, + 3 %, +3%, +4%, and +10%.…”

Nuclear levels and spectroscopy of191Os

et al. 1977

Thirty-nine states, all except two of which are new, have been observed up to 1535 keV in 191Os using the reactions 19~ p)~91Os, 192Os(d, t)a9~Os with 12 MeV deuterons and magnetic analysis with photographic emulsions of the outgoing particles, and ~9~ 7)~91Os with thermal neutrons and three modes of gamma detection in the energy range from 40 keV to ~ 6 MeV. The neutron separation energy was determined as 5758.5___2.0 keV in agreement with the value of the (d,p) reaction. The Q value for the (d, t) reaction was determined as -1265 _+15 keV. Spins and parities are assigned for most of the states below 800 keV. The states below 463 keV are shown to be qualitatively but not quantitatively consistent with the expectations of the Nilsson model. Nilsson systematics of the 1/2-]510[ and 3/2-[512[ orbitals in odd-A Os isotopes with increasing neutron number can be understood in terms of decreasing deformation. Anomalously large (d, p) and (d, t) cross sections populating 5/2-and 3/2-states at 134 and 142 keV, respectively, are explained as a tendency to restore the cross sections expected for a spherical nucleus. Evidence for triaxiality in 19lOs is observed in the form of a 5/2-state at 273 keV which appears to be a rotational state built on the 9/2-ground state.
