    Notizen: Abstract Theg factors of the first excited 2+ levels in the neutron-rich nuclei102Mo and104Mo have been studied through the measurement of the perturbed angular correlations for theγ-γ cascades between the 0 2 + -2 1 + -0 1 + level sequences. The results of g=0.42±0.07 for102Mo and ofg= −0.11 +0.12 for104Mo agree with the prediction of the vibrational-rotational model. In terms of IBA, with the assumption ofN π=3 for the Mo isotopes which takes into consideration a two particle, two-hole excitation across the Z=40 subshell, the proton-bosong factor is deduced to beg π=1.00±0.23. It is shown that this value provides evidence for subshell effects in100Zr.

    Notizen: Abstract: The decays of 112Rh g and 112Rh m obtained as on-line mass separated fission products have been investigated by standard β and γ spectroscopic techniques and γ-γ angular correlations. Low-lying 0+ and 2+ states are identified in the daughter nucleus 112Pd. Systematics suggests the existence of an intruder band which is the lowest in 110Pd, i.e. two neutrons before the midshell.

    Notizen: Abstract: Very neutron–rich fission products of the mass chain A=113 obtained from the IGISOL on–line mass separator have been investigated by γγ coincidence techniques and γ-spectra multiscaling. Gamma–rays following β–decay of 113Tc have been observed for the first time and a new 0.5 s isomeric state has been found in 113Ru.

    A new high-spin isomer in 39 97 Y58 (1986)

    Notizen: Abstract An isomeric state at 3,523 keV excitation energy in97Y with a half-life of 144(10) ms has been discovered with the fission-product separator JOSEF. This isomer is depopulated through aγ transition of 162 keV. AnE3 multipolarity for this transition is consistent with the measured conversion coefficients ofα K =0.98(20) andα T =1.00(19). Subsequent electromagnetic transitions populate several new97Y levels which have high spins. For the isomer the three-quasiparticle configuration [πg 9/2⊗ν(h 11/2,g 7/2)]27/2− is proposed. TheE3 transition with a strength about 2 single-particle units is supposed to be of the typeh 11 2/+1 →d 5 2/−1 . These findings provide evidence for the rapid shape transition atA≃100 since they indicate shell-model character of 39 97 Y58 even at high excitation energies while the immediate neighbour 39 98 Y59 contains a rotational band based on a level at 495 keV.

    The decay scheme of the 3-s Isomer of100Nb and the properties of levels in100Mo (1987)

    Notizen: Abstract Theβ − decay of the longer-lived isomer in100Nb has been studied at the fission-product separator JOSEF. Measurements ofγ-ray singles spectra, ofγ-γ coincidences and ofγ-γ angular correlations have been performed. A value oft 1/2=2.99(11)s has been determined for the isomer which probably hasI π=4+ or 5+. A scheme of the levels of100Mo which are populated in the decay of this isomer has been established. Information on the spins of several states of100Mo has been obtained. Thus,I=0 levels have been identified at 1,505, 2,038 and 2,087 keV. The mixing ratios have been determined for the 22 +→21 + and 23 +→21 + transitions. The results provide evidence for a vibrational structure of100Mo with separate bands based on the ground state and on the first excited 0+ level.
