Atomic parity non-conservation in francium: The FrPNC experiment at TRIUMF Conference Paper uri icon


  • The FrPNC Collaboration is constructing an on-line laser cooling and trapping apparatus at TRIUMF to measure atomic parity non-conservation (PNC) and nuclear anapole moments in a series of artificially produced francium isotopes. Francium's simple electronic structure and enhanced parity violation make it a strong candidate for precision measurements of atomic PNC: the optical PNC and anapole-induced PNC effects are expected to be an order of magnitude larger in francium than in cesium. Atomic PNC experiments provide unique high precision tests of the Standard Model's predictions for neutral current weak interactions at very low energies. Furthermore, precision measurements of nuclear anapole moments probe inter-nucleon weak interactions within the nucleus. Societ Italiana di Fisica.
