Аннотация
The electron-phonon interaction function in Na and K is calculated from first principles using only the pseudopotential for the electron-phonon interaction. The calculations for Na are done for two lattices (b.c.c. and f.c.c.) and also for K with changes in the pseudopotential. Good agreement is observed between the calculated functions and the experimental data.
