We measured compressibility and splay elastic moduli, and the mobility of dislocations of the lamellar phase of C12E5-H 2O system. The compressibility modulus has a usual value (2.5 x 10 7 dyn/cm2) while the splay modulus is small (6 x 10 -8 dyn) and the mobility is high (6 x 10-7 cm2 sg-1). These results are used to calculate the permeation coefficient. These values are then discussed with respect to the presence of defects, revealed by former studies [11].Nous avons mesuré les modules de compressibilité et de divergence ainsi que la mobilité des dislocations dans la phase lamellaire du système C12E5-H2O. Le module de compressibilité a une valeur classique (2,5 x 107 dyn/cm2) alors que le module de divergence est petit (6 x 10 -8 dyn) et q...
