Abstract
Simultaneous magnetic-deformation and light-scattering studies of the nematic bend and twist constant exponents respectively suggest that the nematic-smectic- critical point is weakly anisotropic, in disagreement with all theories of the nematic-smectic- transition. This study also suggests that the bend exponent is universal and very close to the helium value.
