Abstract

The reduced transition probability B(E2;0_gs⁺→ 2₁⁺) for the proton-rich nucleus ²⁸S was determined experimentally using intermediate-energy Coulomb excitation. The resultant B(E2) value 181(31) e²fm⁴ 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 ₁⁺ transition in ²⁸S was obtained to be 1.9(2) by evaluating the M_n value from the known B(E2) value of the mirror nucleus ²⁸Mg, showing the hindrance of proton collectivity relative to that of neutrons. These results indicate the emergence of the magic number Z = 16 in ²⁸S.
