The density of ground‐state mercury ions in the cathode region of a fluorescent‐lamp‐like discharge is measured using laser‐induced fluorescence (LIF) at 194.2 nm. LIF is used to make relative density measurements with good spatial resolution

The purpose of studying excited level lifetimes is to determine the absolute radiative transition probabilities (or oscillator strengths) needed for quantitative spectroscopy and tests of fundamental quantum mechanical principles. The transition prob

Radiative lifetimes for 47 levels in neutral silicon are reported. Lifetimes are measured using time-resolved laser-induced fluorescence (LIF) on a beam of silicon atoms. The transitions studied span the spectral range 160--410 nm. The experimental m

Experimental and theoretical work on the cathode region of a cold-cathode helium glow discharge is described. A current balance, or ratio of ion to electron current, at the cathode is deduced from precise electric field maps and gas density measureme

We use time-resolved laser-induced fluorescence to measure the lifetime of 186 Fe levels with energies between 25 900 and 60 758 cm . Measured emission branching fractions for these levels yield transition probabilities for 1174 transitions in the ra
