“…The beam energy and current have been kept at values as mentioned earlier. All the lines recorded in this spectrum are found in the list of classified lines for Kr I [3,4]. However, the list contains many more lines than those observed in the present measurement.…”

“…The spectral lines are resolved by means of a Minuteman 0.5 meter monochromator (Model 305M) with a resolution of 0.7Å and the photons are detected with a cooled Hamamatsu R943-02 photomultiplier tube. The tables of Stiganov and Sventitskii [3] and Kaufman and Humphreys [4] have been used to identify the transitions. The time resolution (FWHM) of the whole system is measured by the method described by Erman [5] and is found to be 2.8 ns.…”

The radiative lifetimes of some levels belonging to the 4d, 5d and 6d configurations of Kr I have been measured using high frequency deflection technique with a delayed coincidence single-photon counting arrangement. The measurements have been performed under conditions where pressure dependent effects are negligible. Lifetimes of some of the levels have been measured for the first time. A comparison with other results is presented.

New single-photon spectra of jet-cooled Kr2 between ∼98 700 and 99 900 cm−1 have been recorded with an extreme ultraviolet laser generated by four-wave sum-mixing in Xe gas. Molecular ions created by (1+1′) resonance enhanced multiphoton ionization, and daughter atomic ions created by excited state predissociation prior to ionization were mass dispersed and detected in a time-of-flight mass spectrometer. Analyses of the subsequent single isotopic spectra have resulted in vibrational numbering and constants for eight band systems of Kr2 that dissociate to Kr(1S0)+Kr*(4d,5p′,6s). Excited state bond lengths were estimated by Franck–Condon factor intensity simulations. When possible, electronic symmetry assignments for the states were established by correlation diagrams constructed from angular momentum arguments. Possible reasons are discussed for the deviations observed for the shape of many of the observed Rydberg state potential energy curves from their expected nonbonding form.

Magnetic dipole transitions from the metastable ls5 (3P2) state to the ls4 (3P1) state in atomic krypton and xenon have been detected and measured using the technique of intracavity laser magnetic resonance spectroscopy with CO2 laser lines in the 10 μm region. The excited atoms were produced by a low voltage dc discharge in a flow of helium carrier gas. Precise values for the Kr and Xe ls4– ls5 interval and for the magnetic gj-factor of ls4 in Kr were determined in an analysis of the observed spectra.
