At the highest spins, {sup 238{endash} 240}Pu are found to exhibit properties associated with stable octupole deformation, suggesting that a transition with spin from a vibration to stable deformation may have occurred. {copyright} {ital 1999} {ital The American Physical Society}}, number={11}, journal={PHYSICAL REVIEW LETTERS}, author={Wiedenhover, I and Janssens, RVF and Hackman, G and Ahmad, I and Greene, JP and Amro, H and Bhattacharyya, PK and Carpenter, MP and Chowdhury, P and Cizewski, J and et al.}, year={1999}, month={Sep}, pages={2143–2146} } @article{lopez-martens_dossing_khoo_korichi_hannachi_calderin_lauritsen_ahmad_carpenter_fischer_et al._1999, title={Strength distribution of gamma-transitions deexciting superdeformed rotational bands}, volume={647}, ISSN={["0375-9474"]}, DOI={10.1016/S0375-9474(99)00012-3}, abstractNote={The strength distribution of the γ rays in the decay-out from superdeformed (SD) states is investigated by applying the maximum likelihood method, with special emphasis on the influence of the lower threshold given by experimental conditions. Clear graphical solutions are found, and a careful estimation of the dispersion in the values of the number of degrees of freedom and of the average strength of the most likely χ2 distribution is carried out. For the 194Hg nucleus, 41 primary transitions from the decay-out of SD states are identified above 2600 keV. It is concluded that they represent the strongest 10% of the transitions selected stochastically from a Porter-Thomas distribution. This would support the scenario of a statistical decay of SD states via coupling to a compound state at normal deformation. However, the occurrence of several very strong direct one-step transitions as previously observed in 194Hg has a very small probability of the order of 10−4. This may indicate special selection rules governing the decay. However, based on the absence of strong primary transitions from SD states in adjacent nuclei, the situation in 194Hg is viewed as a very lucky incidence.}, number={3-4}, journal={NUCLEAR PHYSICS A}, author={Lopez-Martens, AP and Dossing, T and Khoo, TL and Korichi, A and Hannachi, F and Calderin, IJ and Lauritsen, T and Ahmad, I and Carpenter, MP and Fischer, SM and et al.}, year={1999}, month={Mar}, pages={217–245} } @article{hackman_khoo_carpenter_lauritsen_lopez-martens_calderin_janssens_ackermann_ahmad_agarwala_et al._1998, title={Comment on "Spins, parity, excitation energies, and octupole structure of an excited superdeformed band in Hg-194 and implications for identical bands" - Hackman et al. reply}, volume={80}, ISSN={["1079-7114"]}, DOI={10.1103/PhysRevLett.80.4611}, abstractNote={A Reply to the Comment by R.
