Abstract

Marked pretransition softening is reported of the smectic layer elasticity near the weakly first-order smectic-

A

-nematic phase transition in

N - p - cyanobenzilidene - p - n - octyloxyaniline

(CBOOA). In addition, it is demonstrated that CBOOA will not support a static layer strain. This new relaxation process is studied in detail.
