Abstract : We have implemented the so-called λ-Zeeman technique LZT to investigate individual hyperfine transitions between Zeeman sublevels of the Rb atoms in a strong external magnetic field B in the range of 2500 − 5000 G recently it was established that LZT is very convenient for the range of 10 − 2500 G. Atoms are confined in a nanometric thin cell NTC with the thickness L = λ, where λ is the resonant wavelength 794 nm for Rb D1 line. Narrow velocity selective optical pumping VSOP resonances in the transmission spectrum of the NTC are split into several components in a magnetic field with the frequency positions and transition probabilities depending on the B-field. Possible applications are described, such as magnetometers with nanometric local spatial resolution and tunable atomic frequency references.
