    Notes: Abstract: A high-spin level structure of the nucleus 154Tm has been established for the first time up to 6.14 MeV. The 118Sn + 40Ca reaction at 205 MeV associated with the recoil shadow method was used to identify the I π = (19)+ isomeric state at 2.74 MeV. In-beam γ-ray and conversion electron spectroscopy have been applied on the 144Sm(14N, 4n)154Tm reaction at 95 MeV to build the level scheme. The level structure of 154Tm is compared to other structures observed in N = 85 neighbouring nuclei.

    Configuration assignments and decay of 126La high-spin bands (2000)

    Notes: Abstract: High spin states of 126La have been populated using the reaction 116Sn+14N at 68 MeV. γ-rays and conversion electrons were detected with the GAREL array. Multipolarities of the lowest-lying in-band dipole transitions have been determined from the deduced internal conversion coefficients. Experimental B(M1)/B(E2) ratios have been derived for the bands and compared with calculated values using the Dönau-Frauendorf geometrical model. Configurations are proposed for the bands comparing them with cranked shell model calculations and on the basis of the measured B(M1)/B(E2) ratios. The β-decay of 126La has also been revisited. The population of the 126Ba levels gives a probable spin value of five for the decaying high-spin 126La state with T 1/2≈ 64 s which may indicate a signature inversion in the πh11/2νh11/2 band.
