Energy weighted sum rules for Gamow-Teller and MI excitations are evaluated in three double closed nuclei (4He, 16O, 40Ca) with a phenomenologically correlated ground state. A strong dependence of these sum rules on tensor correlations is shown for Gamow-Teller and magnetic dipole operators, both isoscalar and isovector.

Abstract
Energy weighted sum rules for Gamow-Teller and MI excitations are evaluated in three double closed nuclei (4He, 16O, 40Ca) with a phenomenologically correlated ground state. A strong dependence of these sum rules on tensor correlations is shown for Gamow-Teller and magnetic dipole operators, both isoscalar and isovector.File in questo prodotto:
