Micron-thick spectroscopic cells for studying the Paschen-Back regime on the hyperfine structure of cesium atoms

It is shown that the use of spectroscopic cells of micron thickness ( L = 10–50 μm) allows one to effectively study the behavior of individual levels of the Cs D 2 line in strong magnetic fields up to 9 kG. In particular, the absorption spectrum of Cs excited by circularly polarized light in fields...
