| 英文摘要 | The reduced transition probability B(E2;0(gs)(+) -> 2(1)(+)) for the proton-rich nucleus S-28 was determined experimentally using intermediate-energy Coulomb excitation. The resultant B(E2) value 181(31) e(2)fm(4) is smaller than those of neighboring N = 12 isotones and Z = 16 isotopes. The double ratio vertical bar Mn/Mp vertical bar/(N/Z) of the 0(gs)(+) -> 2(1)(+) transition in S-28 was obtained to be 1.9(2) by evaluating the M-n value from the known B(E2) value of the mirror nucleus Mg-28, showing the hindrance of proton collectivity relative to that of neutrons. These results indicate the emergence of the magic number Z = 16 in S-28. |
