A study of the Nd-136 nucleus has been performed with the EUROBALL III mult
idetector to establish the decay-out of the yrast superdeformed (SD) band.
Three discrete linking transitions (754, 1456, and 1493 keV) have been disc
overed, establishing the position of the SD band at 7.03 MeV excitation ene
rgy with proposed spin and parity 17((-)) for the lowest observed SD state.
Neutron pairing gap parameters for SD shapes have been extracted in Nd iso
topes, using the strong-coupling model and odd-even mass difference formula
s. The major conclusion of our phenomenological analysis is that the pairin
g correlations do subsist in the SD configurations of nuclei in the A = 130
mass region. [S0556-2813(99)01312-6].
