Abstract

The static quadrupole moment

Q_{2^{+}}

for the 1.982-MeV

2_{1}^{+}

state in

{}^{18}O

has been remeasured via Coulomb excitation. Anomalously large

Q_{2^{+}}

values previously published are shown to be erroneous as a result of Coulomb-nuclear interference and other problems eliminated by the present techniques. Both present and previous data are consistent with

Q_{2^{+}}

values of -

{3.1}_{- 2.0}^{+ 3.0}

{0.1}_{- 2.0}^{+ 3.0}

)

e \cdot {fm}^{2}

for constructive (destructive) interference. This result agrees with shell-model and coexistence-model predictions.
