The sub-natural-width N-type resonance in Λ-system, on the D₂ line of Cs atoms is studied for the first time in the presence of a buffer gas (neon) and the radiations of two continuous narrow band diode lasers. L = 1 cm long cell is used to investigate N-type process. The N-type resonance in a magnetic field for ¹³³Cs atoms is shown to split into seven or eight components, depending on the magnetic field and laser radiation directions. The results obtained indicate that levels Fg = 3, 4 are initial and final in the N resonance formation. The experimental results with magnetic field agree well with the theoretical curves.
