Parity Nonconservation in Odd-isotopes of Single Trapped Atomic Ions

TL;DR

This paper estimates parity nonconservation effects in specific isotopes of Ba+ and Ra+ ions using advanced many-body perturbation theory, highlighting Ra+ as a more suitable candidate for experimental measurements.

Contribution

It provides new estimates of PNC light-shifts in Ba+ and Ra+ isotopes, employing third order MBPT to calculate nuclear spin dependent amplitudes.

Findings

Ra+ is more favorable than Ba+ for PNC measurements.

The work uses third order MBPT for more accurate amplitude estimates.

The study compares nuclear spin independent and dependent PNC effects.

Abstract

We have estimated the size of the light-shifts due to parity nonconservation (PNC) interactions in different isotopes of Ba+ and Ra+ ions based on the work of Fortson [Phys. Rev. Lett. 70, 2383 (1993)]. We have used the nuclear spin independent (NSI) amplitudes calculated earlier by us [Phys. Rev. Lett. 96, 163003 (2006); Phys. Rev. A 78, 050501(R) (2008)] and we have employed the third order many-body perturbation theory (MBPT(3)) in this work to estimate the nuclear spin dependent (NSD) amplitudes in these ions. Ra+ is found to be more favourable than Ba+ for measuring both the NSI and NSD PNC observables.
