    Notes: Abstract An in-beamγ-ray study performed with the114Cd(30Si,p 3n) reaction has established the structure of theN=79 nucleus140Pm. States up toI=(20)ħ and 5.5 MeV excitation energy have been recognized above the 5.95 m isomeric state which we identify, from the GT decay to140Nd, as the 8− member of the (πd 5 2/−1 vh 11 2/−1 ) multiplet, changing the present 7− assignment. The low energy part of the level scheme is discussed in terms of the coupling of the valence holes in respect to theZ=64,N=82 shell closure. A new 8+ isomeric state witht 1/2=1 −0.5 +1 ns has been observed, having most likely a (πh 11/2 vh 11/2 -1 )8 configuration.

    g-Factor of the first 2+ state in theN=82 nucleus138Ba (1987)

    Notes: Abstract The 2 1 + level of138Ba has been Coulomb excited with a 105 MeV32S beam. The precession of the gamma ray angular distribution induced by the transient magnetic field when traversing a 2.14 mg/cm2 iron foil, has been measured to be 15.6(1.7) mr. A value of g(138Ba 2 1 + )=0.72(11) was obtained assuming for the transient field strength the Chalk River calibration. The field parametrization has been checked using the first 2+ state in150Sm as probe. Theg value obtained is sensibly lower than predicted by large scale shell model calculations in a proton subspace. Theg-factor of the first 2+ state in148Sm has been remeasured yieldingg(148Sm 2 1 + )=0.246(22).
