We report the first measurements of the average electric dipole polarizabilities of five alkali halide dimers. A combined monomer-dimer molecular beam deflection pattern in an inhomogeneous electric field is subject to an appropriate computational analysis to extract the polarizabilities. A simple combination of bond and effective ionic models to estimate the polarizabilities gives reasonably good agreement with the measured values. The values are, in units of 10/sup -24/ cm/sup 2/, (KF)/sub 2/:25.3 +- 3.2; (KCl)/sub 2/:28.6 +- 3.0; (RbCl)/sub 2/:43.4 +- 4.2; (CsCl)/sub 2/:36.6 +- 5.0; (CsF)/sub 2/:21.2 +- 2.6.
