A multilayer neutron monochromator-polarizer is proposed, consisting of alternating layers of the alloy 66% Ni/sup 62/--34% Fe/sup 54/ and of vanadium, obtained by thermal sputtering in vacuum. The concentration of the employed alloy prevents total neutron reflection from the proposed monochromator. The parameters of the neutron multilayer monochromator-polarizer are given: relative half-width of reflection 25%, maximum reflection coefficient 75%, polarizing efficiency P approx. = (90--95)%. The experimental dependences of the reflection coefficient and of the polarizing efficiency of the monochromator-polarizer on the neutron wavelength are also given.
