Investigation of nearly degenerate opposite parity states in atomic dysprosium

Abstract
A pair of closely lying states of opposite parity and the same total electronic angular momentum J=10 at 19 797.96 cm1 in dysprosium are experimentally investigated with the goal of evaluating parameters relevant to P and P,T violation experiments. Measurements of lifetimes, electric polarizability, and energy intervals between isotope and hyperfine components are presented.
