Direct Wavelength Measurement of the Visible M1 Transition in Ba7+ with a Novel Calibration Method

Direct Wavelength Measurement of the Visible M1 Transition in Ba7+ with a Novel Calibration Method

We observed and directly measured the M1 transition between the two states of the fine structure splitting in the ground state of Ba7+ with a visible spectrometer coupled to a compact electron beam ion trap. To validate the measurement accuracy, we demonstrated a calibration method using Ar+ emissio...

Zusammenfassung:We observed and directly measured the M1 transition between the two states of the fine structure splitting in the ground state of Ba7+ with a visible spectrometer coupled to a compact electron beam ion trap. To validate the measurement accuracy, we demonstrated a calibration method using Ar+ emissions from buffer gas. The wavenumber in vacuum was determined to be 23591.57 (15) cm−1.
