“…For the target excitation the B(E2, 0+ -+ 2+) in 206pb is known [5], but the static moment of the 2+ state is not, so that w,e assumed Q(206pb , 2:t) =o.o±o.5IQr{206pb, 2+)1. This assumption introduces some i uncertainty into the result; ,however, as di.scussed in the previous paper [1], this method of comparing with target excitation measured simultaneously has a number of advantages.…”

“…For instance, it is possible to deduce the moment of inertia parameter Aee of the even-even "core" of 159Tb from the value of A 0= 12.64 keV and of the other parameters[2,6,22]:where AE-E1/2-E3/2.This result compares favourably with the experimental moment of inertia parameter of 158Gd, i.e. Furthermore, the resulting fitted parameters have quite reasonable values.…”

“…The recoil velocity along the beam axis, deduced from the distance between the shifted and unshifted lines using the formulation of Qu6bert et al [22], has been found to be (3.264-0.06)% of c. The experimental values of R, corrected for the above-mentioned effects, and the calculated ones are compared in Fig. 6.…”

The ground-state band of 159Tb has been Coulomb excited up to spin 23/2 by 151-MeV 4~ions. The lifetimes of the 9/2 to 23/2 levels have been determined by combining results obtained with the RD and DSA methods, the E2/M1 mixing ratios for AI=I transitions have been measured using angular correlation techniques and the branching ratios for the levels up to spin 17/2 have been determined. The energies of the levels and the reduced M1 and E2 transition probabilities for their decay have been compared with the predictions of the rotational model, without and with AK= 1 admixtures. No satisfactory agreement could be achieved for all available experimental data simultaneously.

“…The total counts in the peaks of the singles y-ray spectrum were obtained by integrating the spectrum after the background was subtracted, as discussed in section 4. To compare the experimental results with the theoretical calculations, the yields in the unit of b/sr•mg/cm 2 were calculated according to the formula (8) where N 1 is the number of counts in the peak I, ~~ is the solid angle of the y-ray detector in sr, E is the absolute photopeak efficiency of the detecto~ £ is the percentage live time of the data acquisition system, Q…”

The lifetimes .and reduced transition probabilities for spins .6+-18+ in the ground-state rotational band of 232 Th have been measured by recoil-distance, Doppler-broadened lineshape, and multiple Coulomb excitation methods using 84 Kr and 136 Xe projectiles. Within the limits of experimental uncertainty, transition probabilities from all of the methods are consistent with those of a good rotor ~or spins 6+-18+ .. The discrepancy with the prediction of simple B-band mixing and centrifugal stretching models is discussed. NUCLEAR REACTIONS: 2 32 Th(84 IU-, 84 Kr', y), ELAB = 385 MeV; 2 32 Th (136 Xe, 136 Xe' ,y) ELAB = 595,623 MeV; measured lifetimes for 6+-18+ members g. s. band by recoil-distance and Doppler-broadened lineshape methods; yields for Coulomb excitation measured; B(E2) values derived from lifetimes and yields, compared to theory.
