Paschen-Back Effect

The Paschen-Back effect refers to a phenomenon in atomic physics where the energy levels of atoms change due to the influence of a strong magnetic field. In this context, it affects hyperfine structure, which is the small shifts in energy levels caused by interactions between nuclear spins and electron spins. When a magnetic field is applied, the energy levels split into different patterns compared to weaker fields, allowing scientists to observe and measure these changes. This effect helps researchers understand the atomic structure and interactions more precisely, particularly in the presence of intense magnetic environments.
