Abstract
Electron diffraction shows that a free-standing two-layer film of N-(4 -n-butoxybenzylidene)-4-n-octylaniline exhibits smectic-A, hexatic-B, and crystal-B phases upon cooling. The hexatic-B is preceded by a phas e, called hexatic-B-1, with hexatic-like positional correlations but n o sixfold symmetric arcs in its diffraction pattern. The smectic-A-hex atic B-1 transition is accompanied by a strong heat-capacity and optic al-reflectivity anomaly.
