Abstract

We estimate the relative contribution of nuclear structure and new physics couplings to the parity nonconserving spin-independent effects in atomic systems for both single isotopes and isotopic ratios. General expressions are presented to assess the sensitivity of isotopic ratios to neutron skins and to couplings beyond standard model at tree level. The specific coefficients for these contributions are calculated assuming Fermi distribution for proton and neutron nuclear densities for isotopes of Rb, Cs, Ba, Sm, Dy, Yb, Tl, Pb, Fr, and Ra. The present work aims to provide a guide to the choice of the best isotopes and pairs of isotopes for conducting atomic parity-nonconserving measurements.
