“…B=background activity angular distributions, time spectra with respect to the beam pulses and four-parameter coincidence spectra. In the conversion-electron measurements we employed an intermediate-image magnetic plus Si(Li) electron spectrometer [23]. The resolution for 300-900 keV electrons was below 3.0 keV.…”

Levels of 135pr populated in the (p, 2n) reaction were studied using methods of in-beam y-ray and conversion electron spectroscopy. Many low-lying positive-parity states give evidence of a deformation of/~=0.15-0.20. The same conclusion is evident from band structures built on these positive-parity states and on the h~1/2 negative-parity state. The triaxial rotor-plus-particle model reproduces quite well band structures with /~=0.20 and ~=21 ~

“…In 7-ray spectroscopy we used 1-10 cm 3 planar and 7-25% coaxial Ge(Li) and hyperpure Ge detectors. In-beam conversion electron spectra were measured employing an intermediate-image magnetic beta spectrometer combined with a cooled Si(Li) detector [25] which gave a resolution of 2.5-3.0 keV for 200-700 keV electron lines.…”

“…In our electron spectrometer, the detected electrons leave the target at an average angle of 50 ~ and therefore the corrections for angular distribution effects are not necessary [25]. The electron spectra were normalized to the v-ray intensities with the aid of the 997keV 13/2+-,7/2 -E3 ground state transition.…”

Levels of the N= 83 nucleus ~47Gd have been investigated by methods of in-beam 7-ray and conversion electron spectroscopy using the a4VSm(3He, 3n) and a44Sm(~,n) reactions. Sixteen new low-and medium-spin levels have been observed in a47Gd. We have located six members of the v f7~2 x 3-particle-octupole septuplet and several neutron single-particle states in ~47Gd. The levels of l~7Gd are discussed on the basis of the spherical shell model.

Electromagnetic transitions from low-lying 0 +, 2 +, 4 + and 3-states in lO2, a04pd have been studied using (p, 2n) and (p,p') reactions and Coulomb excitation. The E2 transition probabilities from the 0 + state in ~~ (13 W.u.) and from the 0 + state in ~~ (14 W.u.) are somewhat low for two-phonon states. Generally, the E2 transition rates are reasonably well reproduced by the IBA-2 and by the boson-expansion description. The intruding 0 + state (tl/2 = 14.3 ns) in l~ is connected to the 2 + and 2~-states via strong E2 transitions: B(E2; 0+~2+)=96___40W.u.; B(E2; 2~-~0+)=17 ill W.u.
