Measurement of the scalar Stark shift of the61S063P1transition in Hg

Abstract
The scalar Stark shift of the 254-nm intercombination 61S063P1 line in Hg was measured using a Doppler-shift frequency calibration technique. It is equal to 3.32±0.06 kHz/(kV/cm)2. This measurement can be used to test more accurate calculations of Hg atomic wave functions.
