Algebraic approach to nuclear quasimolecular spectra

Abstract

It is suggested that nuclear quasimolecular spectra are dominated by dipole rather than quadrupole degrees of freedom. An algebraic approach to these dipole modes in terms of the group U(4) is proposed. One of the dynamical symmetries of the corresponding algebraic structure, O(4), is discussed and shown to yield spectra of molecular rotation-vibration type.NUCLEAR REACTIONS Quasimolecular spectra, algebraic approach, O(4) symmetry.
