Isotope Shift

Isotope shift refers to the slight differences in the energy levels of atoms that come from variations in their isotopes, which are atoms of the same element with different numbers of neutrons. These differences can affect the light emitted or absorbed by the atoms. In hyperfine structure, isotopes can also influence magnetic interactions within the nucleus, leading to shifts in energy levels. This phenomenon helps scientists identify and study isotopes, enhancing our understanding of atomic structure and the fundamental forces at play in the nucleus.
