内容記述	NUCLEAR STRUCTURE AND DYNAMICS 2012 9–13 July 2012 The reduced transition probability B(E2;O^<+>_<gs> → 2^<+>_<l>) for the proton-rich nucleus ^<28>S was determined experimentally using intermediate-energy Coulomb excitation. The resultant B(E2) value 181(31) e^2fm^4 is smaller than those of neighboring N = 12 isotones and Z = 16 isotopes. The double ratio \|M_n\|M_p\|/(N/Z) of the 0^<+>_<gs> → 2^<+>_<l> transition in ^<28>S was obtained to be 1.9(2) by evaluating the M_n value from the known B(E2) value of the mirror nucleus ^<28>Mg, showing the hindrance of proton collectivity relative to that of neutrons. These results indicate the emergence of the magic number Z = 16 in ^<28>S.
