Abstract Using neutron diffraction the magnetic form factor f of oxygen is investigated in the solid monoclinic α‐phase ( T < 23.88 °K). The antiferromagnetic reflections of α‐O 2 (001) and (100), containing the purely spin magnetic scattering on π‐electrons, may give the values of f for sin θ/γ equaling to 0.1047 and 0.1242, respectively. The data of magnetic diffraction on KO, are also considered: in the magnetic structure proposed the antiferromagnetic reflections (001) and (110) (sin θ/γ is equal to 0.0735 and 0.1260, respectively) are again due to the orientation of the π‐orbital spin moments (orbital moment is frozen). The whole set of obtained values f for O 2 and O 2 are in reasonable agreement with the calculated dependences of f .
