Laser spectroscopy and CP-violation sensitivity of actinium monofluoride. [PDF]

Nature
The apparent invariance of the strong nuclear force under combined charge conjugation and parity (CP) remains an open question in modern physics1,2. Precision experiments with heavy atoms and molecules can provide stringent constraints on CP violation ...

Update of Atomic Data for the First Three Spectra of Actinium

Atoms, 2022
The present article describes a complete reanalysis of all published data on observed spectral lines and energy levels of the first three spectra of actinium (Ac I–III). In Ac I, three previously determined energy levels have been rejected, 12 new energy

Gamma counting protocols for the accurate quantification of 225Ac and 213Bi without the need for a secular equilibrium between parent and gamma-emitting daughter

EJNMMI Radiopharmacy and Chemistry, 2022
Background Quantification of actinium-225 through gamma counter measurements, when there is no secular equilibrium between actinium-225 and its gamma emitting daughters bismuth-213 and/or francium-221, can provide valuable information regarding the ...
