Measurement of the static quadrupole moments of the first $2^{+}$ states in ${}^{94}{Mo}$ , ${}^{96}{Mo}$ , ${}^{98}{Mo}$ , and ${}^{100}{Mo}$

The static quadrupole moments

Q_{2^{+}}

and the

B (E 2; 0^{+} \to 2^{+})

values of the first

2^{+}

excited states in

{}^{94}{Mo}

{}^{96}{Mo}

{}^{98}{Mo}

, and

{}^{100}{Mo}

have been determined by Coulomb excitation experiments performed by resolving elastically and inelastically backward scattered

{}^{4}{He}

and

{}^{16}O

projectiles detected in four surface barrier detectors. The measurements yielded for

Q_{2^{+}}
