A beam of lithium atoms in the ground state with a maximum kinetic energy Wк = 0.1 eV passes through a Stern-Gerlach magnet of length l = 6 cm with a gradient dB/dx = 5 T/cm. In front of the magnet there are two identical diaphragms S (figure) at a distance L = 1 m from one another. At what maximum diaphragm size will the components of the split beam be completely separated?
