Tune-out wavelengths for metastable helium

James Mitroy, Li Yan Tang

    Research output: Contribution to journalArticlepeer-review


    The six longest tune-out wavelengths for the He(1s2s3Se1) metastable state are determined by explicit calculation. The tune-out wavelength at 413.02 nm is expected to be sensitive to finite mass, relativistic, and quantum electrodynamic effects upon the transition matrix elements and its measurement would provide a nonenergy test of fundamental atomic structure theory.
