“…The SCK2 moments are rather constant with spin, as one would expect for a superdeformed band, while the LN ones vary somewhat more. The LN results are in good agreement with the experimental data of 17.5 ± 0.2 eb [23] whereas the SCK2 are slightly higher. In panel (c) the transition energies are shown, though both approaches provide good results as compared with the experimental data [24] the SCK2 ones are slightly better.…”

Kamlah's second order method for approximate particle number projection is applied for the first time to variational calculations with effective forces. High spin states of normal and superdeformed nuclei have been calculated with the finite range density dependent Gogny force for several nuclei. Advantages and drawbacks of the Kamlah second order method as compared to the Lipkin-Nogami recipe are thoroughly discussed. We find that the Lipkin Nogami prescription occasionally may fail to find the right energy minimum in the strong pairing regime and that Kamlah's second order approach though providing better results than the LN one may break down in some limiting situations.

“…The side-feeding model discussed above is similar in form to that found appropriate in the feeding of SD bands [24], and was chosen to produce plausible mean time delays associated with the feeding of these bands. There is clearly an uncertainty associated with this model.…”

“…The mean velocity of the recoiling nuclei was calculated as a function of time by integrating over the target and averaging over 100 reaction locations within the target. The decay of the nucleus was modeled by assuming a constant in-band Q t , and side feeding into each state was modeled by a single transition with the same lifetime as the precursor in-band state [22] and an intensity to match the observed intensity profile of the band. The fractional shifts calculated in this model for various Q t values are shown by solid curves in Fig.…”
