The Francium facility at TRIUMF

Abstract

Ground-state properties and static dipole polarizabilities of the alkali dimers from K 2 n to Fr 2 n ( n = 0 , + 1 ) from scalar relativistic pseudopotential coupled cluster and density functional studies Relativistically corrected hyperfine structure constants calculated with the regular approximation applied to correlation corrected ab initio theory Abstract. We present the current status of the Francium Trapping Facility at ISAC at TRIUMF. The facility will enable future experiments on the weak interaction with measurements of atomic parity non-conservation laser-cooled samples of artificially produced francium. These experiments require a precisely controlled environment, which the facility is designed to provide. The facility has been constructed and is being prepared for a series of commissioning runs.

Nuclear-spin-dependent parity nonconservation ins-d5/2ands-d3

“…Several proposals have been put forward to search for PNC in heavier atoms, where the PNC signal is expected to be larger (e.g. [14][15][16][17][18]), and in systems such as Rb [19], where the accuracy could be higher. A promising alternative is to perform measurements of PNC in a chain of isotopes [20], where the accuracy is limited only by the knowledge of the (poorly understood) neutron distribution.…”

“…Thus, using optically cooled and trapped Fr atoms for the measurements has several advantages. APNC experiments using laser-cooled Fr atoms are currently under way at TRIUMF, Canada [8] and Legnaro National Laboratories, Italy [9].…”
