Spectroscopy, or the measurement of the wavelengths of light that materials emit or absorb, is a standard way to probe characteristics of materials, including what energy levels their electrons can assume. However, spectroscopy of heavy elements, such as artificially made fermium, element number 100, is difficult because such substances are scarce and ...
