Abstract
We observe for the first time rotational bands of enhanced deformation (ED) in 127Pr and 128Pr, and suggest that these bands are built upon πg9/2 ([404]92) in 127Pr and on the πg9/2νh11/2 orbitals in 128Pr. These are the lightest isotopes of Pr for which ED bands have been observed. A contrasting trend in the dynamical moments of inertia (J(2)) versus N is observed at low frequencies for the “normal-deformed” πh11/2 and “enhanced-deformed” πg9/2 bands of 127–131Pr both experimentally and in self-consistent Woods-Saxon calculations. The trends in J(2) and β2 are correlated with a decreasing probability for pair scattering into the deformation-driving νh9/2/f7/2 ([541]12) orbital.
