ResumoThe quadrupole interaction frequencies ω0 = 3eQ1Vzz41(21-1) h̵ in the 5− state of 118Sn have been measured by time differential perturbed angular correlation technique in Sn, Sb and (95% Sn+5% Sb) environments. The ω0 for 116Sn was determined in Sn environment only. With the help of the known electric field gradient 1) of Sn in a Sn lattice the quadrupole moments have been deduced as Q(5−, 118Sn) = ±0.10(4) b and Q(5−, 116Sn) = ±0.165(60) b. These values together with the known2) quadrupole moment of the analogous 5− state in 120Sn are interpreted in terms of the pure single-particle model. The data exhibit the expected strong systematic variation of QI with the number of particles in the h112. subshell which is being filled with 1, 3 and 5 neutrons in 116Sn, 118Sn, and 120Sn, respectively.
