Elementary quantum mechanics of particle- rotor coupling: K = ½ bands

Particle-rotor coupling in K = ½ bands: influence of “decoupling”--1

The way that pairing modifies the sharp Fermi surface of the shell model Occupancies of shell model states as a function of energy (a). Without a pairing force-- the Fermi surface is sharp (b). With a pairing force-- the pairing force is said to “smear-out” the occupancies. Occupancies of shell model states as a function of energy (a).
