The narrow peak recently found in various pionic double charge exchange (DCX) cross sections can be explained by the assumption of a universal resonance at 2065 MeV, called d ′. We calculate the mass of a six-quark system with J P = 0 − , T = 0 quantum numbers employing a cluster model and a shell model basis to diagonalize the nonrelativistic quark model Hamiltonian.

The recent discovery of isotopes with Z=110–111 suggests evidence for (1) a monopole–monopole interaction that does not appear explicitly in Nilsson– Strutinsky mass systematics, and (2) a competition between SU(2) and SU(3) dynamical symmetries that has been predicted for this region. Our calculations suggest that these new isotopes are near spherical, and may represent a true island of superh...

A detailed understanding of complete fusion cross sections in heavy-ion collisions requires a consideration of the effects of the deformation of the projectile and target. Our aim here is to show that deformation and orientation of the colliding nuclei have a very significant effect on the fusion-barrier height and on the compactness of the touching configuration. To facilitate discussions of f...
