Abstract [en]

A systematic study of the depopulation of superdeformed rotational bands in neutron-deficient A approximate to 80-90 nuclei has been performed. We observed a correlation between the rotational frequency at which the decay out of the superdeformed bands takes place and the difference between the transition quadrupole moments of states in the superdeformed bands and high-lying states with normal deformation. The observation may constitute direct experimental evidence that the commonly adopted tunneling picture for the decay of superdeformed states is valid.
