"Experimental Improvements for Tune-out Wavelength Spectroscopy with 87Rb"Elizabeth Larson , University of Virginia - Department of Physics [Host: Prof. Cass Sackett]
ABSTRACT:
A tune-out wavelength is one at which the dynamical polarizability of an atom is zero; that is, the Stark shifts from higher- and lower-lying states cancel exactly. Measurements of tune-out wavelengths provide vital experimental access to dipole matrix elements, which are currently the limiting factor in improving theoretical calculations of atomic parity violation. I will discuss previous measurements of the scalar and vector tune-outs between the 5P excited states of 87Rb, as well as plans to improve measurement precision and complete a first measurement of the 6P tune-outs. |
