Rotation-induced transition from superfluid to normal phase in mesoscopic systems: [sup 168]Yb and adjacent nuclei

The transition from strong static pairing to weak static pairing and its consequences to the excitation spectrum of a mesoscopic (medium number of particles) system are investigated. New levels have been measured in [sup 168]Yb. A reasonable description of the [ital A][approx]168 isotopes spectra is...

Description
Summary:The transition from strong static pairing to weak static pairing and its consequences to the excitation spectrum of a mesoscopic (medium number of particles) system are investigated. New levels have been measured in [sup 168]Yb. A reasonable description of the [ital A][approx]168 isotopes spectra is obtained. The adequacy of the phase transition concept is discussed.
