The Sp(3,$R$) model and rotational phenomena in light nuclei

The symplectic model, based on Sp(3,$R$)--the smallest algebra containing both the shell model Hamiltonian and the rotor algebra--has a close physical connection both to the microscopic shell model and the collective deformation and rotational degrees of freedom. Symplectic model calculations of light $p$-shell nuclei will be presented and discussed in the context of emerging rotational phenomena in no-core shell model (NCSM) calculations.
