Coulomb Excitation of the First2+State ofMg24

Coulomb excitation of the first excited state of ${}_{}{}^{24}{}_{}{}^{}\mathrm{Mg}$ has been investigated by means of a coincidence experiment using a position-sensitive detector. Interpreting the data according to the semiclassical theory and correcting for quantal effects, we obtained a reduced transition probability of $B(E2; 0^{+}\to 2^{+})=0.042\mathrm{}\pm 0.002 e^2{\mathrm{b}}^2$ and a static quadrupole moment of $Q_{2^{+}}=-0.305\mathrm{}\pm 0.064 e\mathrm{b}$.
