Fig. 1 (IMAGE) Osaka University Caption Transition strengths between spin-0 states for nuclei with atomic masses below 50. The green point shows the strength for the transition between the superdeformed state and the ground state of 40Ca, which has the smallest value. The red points are experimental values, and the dashed line is a curve inversely proportional to the 2/3 power of the mass number A, showing the trend between the spin-0 states with respect to the mass.
