backbending

backbending

[′bak‚bend·iŋ]
(nuclear physics)
A discontinuity in the rotational levels of some rare-earth nuclei around spin 20ℏ (where ℏ is Planck's constant divided by 2π), which appears as a backbend on a graph that plots the moment of inertia versus the square of the rotational frequency.

This is more strikingly revealed when one makes the usual backbending plot of the energies in which the kinematic moment of inertia is plotted against the square of rotational frequency.
The behavior of the octupole band is most clearly illustrated by a conventional backbending plot.
It is found in some rotational deformed nuclei that the transition energy decreases with increasing I, this anomalous behavior is called nuclear backbending.
As for Bigonzetti's grand finale, Cinque, featuring all but Semionova and Malinovskaya, the femmes (though not quite fatales) cavorted on chairs with wigs and hanging tutus, their solos offering preening, backbending, and the occasional wrap-a-leg-around-the-neck trick.
At this level, there are no great heights involved, but several members of the group perform a tricky Gazelle pose, which requires some serious backbending over a trapeze.
