✦ Synopsis

Diffuse S-m? scattering data from BCC solutions of Li-Jig alloys indicate a preference for unlike nearest neighbors.

and the short-range order coefficients have been measured as a function of composition.

Size-effert coefficients have also been determined, and these indicate that individual atoms are displared from the average lattice sites.

The lattice parameter minimum at 63 atomic per cent Li coul&~l with the x-ariatioii of the size-effect coefficients with composition suggests that the I,i-Jig interatomic distance is shorter than the average of the distances between like atoms, and the interatomic tlistanres hare been calculated.
