Effects of three-nucleon forces and scattering states shape exotic isotopes of oxygen and calcium
- State-of-the-art computation of exotic isotopes of oxygen and calcium including the effects of three-body forces and the scattering states.
- Confirmation of experimentally known shell structure and prediction of excited states in isotopes of oxygen.
- Prediction of shell structure in 54Ca (which contains 14 more neutrons than most of the calcium in our teeth and bones).
- 54Ca exhibits only a soft sub-shell closure, and the ordering of single-particle states differs from the traditional shell model.
- The theoretical prediction of the structure of 54Ca was very recently confirmed experimentally at the RIKEN in Japan.
