Abstract (EN): An elastic neutron scattering study of deuterated betaine calcium chloride dihydrate under hydrostatic pressure is presented. It is shown that a previous phenomenological model based on a one¿dimensional order parameter P, and involving a term of the form P2(¿P/¿z)2 remains adequate to account satisfactorily for the effects of the hydrostatic pressure. From the study of the temperature dependence of the integrated intensity of the satellites it is inferred that the critical exponent ß related to the primary order parameter is close to 0.5 for 2.9 × 108, 3.4 × 108, and 4 × 108 Pa.
