Titre |
Beyond Shell Model: Radii, halo orbits and shell structure |
|
Résumé |
The Shell Model is about solving a Schrödinger equation with
suitable interactions. So far, nuclear radii, binding energies and
basic shell structure cannot be explained by the Shell Model. To "go
beyond" means addressing the problem phenomenologically in ways to
make it possible to discover basic mechanisms at play. Our starting
point is the observation that nuclear radii and masses exhibit strong
shell effects associated with "magic numbers" 6,14,28,50,82 and 126.
Their origin is an open problem, difficult to pinpoint in the
case of masses but subsumed by a single phenomenological term that
brings down root mean square deviations with observed radii to 0.01
fermi. The origin of this term is unambiguously traced to the
existence of huge "halo" orbits...
