The $E0\mathrm{}$ branching ratio $\frac{{\Gamma }_{\pi }}{\Gamma }$ of the ${}_{}{}^{32}{}_{}{}^{}\mathrm{S}$ (3.78-MeV, $0^{+}$) state to the ground state was measured to be (3.54 ± 0.62) × ${10}^{-4\mathrm{}}$. When combined with the lifetime ${\tau }_m=(0.90\mathrm{}\pm 0.15)$ psec of this state one obtains the value ${〈M〉}_{\pi }=(2.22\mathrm{}\pm 0.27)$ ${\mathrm{fm}}^2$ for the $E0\mathrm{}$ matrix element.

NUCLEAR REACTION ${}_{}{}^{31}{}_{}{}^{}\mathrm{P}({}_{}{}^3{}_{}{}^{}\mathrm{He}, d)$, $E=8.5\mathrm{}$ MeV; ${}_{}{}^{32}{}_{}{}^{}\mathrm{S}$ measured $E0\mathrm{}$ branching ratio. Deduced $E0\mathrm{}$ matrix element.
