The $B(E2; 0^+_1 \\rightarrow 2^+_1)$ value for the excitation of the first $2^+$ state in \\nuc{104}{Sn} has been measured to be $0.180(37)~e^2$b$^2$ relative to the well-known $B(E2)$ value of \\nuc{102}{Cd}. This result disagrees by more than one sigma with a recently published measurement \\cite{Gua13}.
