Precision Measurement for Metastable Helium Atoms of the 413 nm Tune-Out Wavelength at Which the Atomic Polarizability Vanishes
We present the first measurement for helium atoms of the tune-out wavelength at which the atomic polarizability vanishes. We utilize a novel, highly sensitive technique for precisely measuring the effect of variations in the trapping potential of confined metastable (2S13) helium atoms illuminated by a perturbing laser light field. The measured tune-out wavelength of 413.0938(9stat)(20syst)nm compares well with the value predicted by a theoretical calculation [413.02(9) nm] which is sensitive...[Show more]
