An approach is developed for description of the nonuniform periodic structure in the system of Fermi particles with a shortrange pair interaction potential in the framework of the functional integral and the effective action functiona. Nonstability of the uniform ground state for large pressures is demonstrated as well as nonstability of the weak-nonuniform body-centred structure. Bibl. – 6.
