Physicists aim to investigate the standard model using misshapen radium monofluoride, which could help settle competing nuclear structure models.
Radium monofluoride's unique properties, due to radium-225's unusual atomic characteristics, make it an ideal candidate for this research.
The hyperfine structure of radium monofluoride has been measured with high precision, revealing the effects of the finite size of the nuclear magnetization for the first time.
Some theories of physics beyond the standard model predict that signatures of dark matter or sources of matter–antimatter asymmetry could be detected by tiny shifts in the frequencies of energies of certain states in atoms and molecules.
Author's summary: Researchers use radium monofluoride to probe the standard model.
