The new sugar gemini nonionic surfactant - bis(C12LA) [(C_{56}H_{110}N_{4}O_{22})] was investigated by small angle neutron scattering method for six dilute solutions with concentrations: 20 CMC, 50 CMC, 75 CMC, 100 CMC, 125 CMC and 150 CMC (CMC = 7.3×10^{-6} mol/dm^{3}, CMC = critical micellar concentration) and three temperatures (20°C, 40°C and 60°C) for the q range 0.003-0.4 Å^{-1}. The aim of experiment was to determine the size and shape of micelles as a function of concentration and temperature in heavy water micellar solutions of nonionic dimeric surfactant bis(C12LA).
