Towards 31Mg-β-NMR resonance linewidths adequate for applications in magnesium chemistry
The span of most chemical shifts recorded in conventional 25Mg-NMR spectroscopy is ~ 100 ppm. Accordingly, linewidths of ~ 10 ppm or better are desirable to achieve adequate resolution for applications in chemist...

Development of a polarized 31Mg+ beam as a spin-1/2 probe for BNMR
A 28 keV beam of 31Mg+ ions was extracted from a uranium carbide, proton-beam-irradiated target coupled to a laser ion source. The ion beam was nuclear-spin polarized by collinear optical pum** on the ...

Atomic parity non-conservation: the francium anapole project of the FrPNC collaboration at TRIUMF
We present a method for measuring the nuclear anapole in a string of francium isotopes. The anapole is a parity non-conserving electromagnetic moment that enables parity-forbidden transitions between ground st...
