Abstract

The reduced transition probability B(E2;0gs+→21+) for S28 was obtained experimentally using Coulomb excitation at 53MeV/nucleon. The resultant B(E2) value 181(31)e2fm4 is smaller than the expectation based on empirical B(E2) systematics. The double ratio |M _n/M _p|/(N/Z) of the 0gs+→21+ transition in S28 was determined to be 1.9(2) by evaluating the M _n value from the known B(E2) value of the mirror nucleus Mg28, showing the hindrance of proton collectivity relative to that of neutrons. These results indicate the emergence of the magic number Z=16 in the |T _z|=2 nucleus S28.
