Abstract:Spectral lines of buffer noble gases injected into an electron beam ion trap have recently been used as a reference to aid accurate determination of the wavelengths of optical transitions of highly charged ions. Simultaneous observation of emission lines of highly charged ions along with those of neutral atoms or singly charged ions represents a reliable method for wavelength calibration that suppresses systematic uncertainties. Here, we present visible and infrared emission spectra of buffer Ne and Ar gases in … Show more
