Evidence for superdeformation in 149,150dy : Onset of the collapse of the z=66 deformed shell closure?
(2000) In Physical Review C - Nuclear Physics 61(3). p.373031-373034- Abstract
An experiment has been performed to search for superdeformed (SD) states in 149,150Dy. While no evidence for discrete superdeformed states has been observed, a superdeformed ridge with a separation of ΔΕγ=52 keV with a total intensity of 1.8±0.5% that of 150Dy has been observed. An upper limit of 0.8% (0.9%), of the intensity of 150Dy (149Dy), is placed for observation of the most intense discrete line states. The relative weakness in the SD population is suggested to be due to a rapid decrease in the depth of the superdeformed minimum, as one moves away from doubly magic 152Dy.
