Atomiikka
Atomiikka, Finnish for atomic physics, is the branch of physics that studies atoms as physical systems and their interactions with light and other fields. It concerns the structure of atoms, the behavior of electrons and nuclei, and how atoms respond to electromagnetic interactions. The field overlaps with quantum mechanics, spectroscopy, quantum optics, and metrology, and it underpins much of modern technology.
Key topics include atomic structure and energy levels, electronic transitions and atomic spectra, isotopes and hyperfine
Historically, atomic physics emerged from studies of atomic spectra in the early 20th century, Rutherford’s nuclear
