Abstract
We have carried out a detailed study of the smectic--smectic- transition in butyloxybenzylidene heptylaniline (40.7) using high-resolution x-ray, heat-capacity, and light scattering techniques. Although the order-parameter data are consistent with heliumlike critical behavior, the data as a whole are uniquely described by a mean-field Landau model with an anomalously large sixth-order term.
