# Measuring nuclear-spin-dependent parity violation with molecules: Experimental methods and analysis of systematic errors

@article{Altunta2018MeasuringNP, title={Measuring nuclear-spin-dependent parity violation with molecules: Experimental methods and analysis of systematic errors}, author={Emine Altuntaş and Jeffrey Ammon and Sydney B.

Nuclear spin-dependent parity violation (NSD-PV) effects in atoms and molecules arise from $Z^0$ boson exchange between electrons and the nucleus, and from the magnetic interaction between electrons and the parity-violating nuclear anapole moment. It has been proposed to study NSD-PV effects using an enhancement of the observable effect in diatomic molecules [D. DeMille $\textit{et al.}$, Phys. Rev. Lett. $\textbf{100}$, 023003 (2008)]. Here, we demonstrate measurements of this type with…
