Parity nonconservation in ytterbium ion

Abstract

We consider parity nonconservation (PNC) in singly ionized ytterbium (Yb+) arising from the neutral current weak interaction. We calculate the PNC electric dipole transition amplitude (E1PNC) and the properties associated with it using the relativistic coupled-cluster theory. E1PNC for the [4f14] 2 6s --> [4f14] 2 5d3/2 transition in Yb+ has been evaluated to within an accuracy of 5%. The improvement of this result is possible. It therefore appears that this ion is a promising candidate for testing the standard model of particle physics.
