| Abstract: | An ususually strong magnetic dipole transition from the ground state to a state at Ex = 10.319 MeV in 40Ca has been observed in high-resolution inelastic electron scattering, contrary to expectations from the pure independent particle shell model. The transition strength, however, can be accounted for by coherent spin-flip transitions due to strong ground-state correlations. |
