Interactions between autoionising resonances are described. The authors begin from the
simplest cases, namely isolated autoionising resonances and shape resonances, and build …

This completely revised second edition of the standard work has been expanded by some
twenty percent to include more information on the latest developments and new apparatus …

Vacuum-ultraviolet (VUV) generation by resonant third-order sum–difference frequency
conversion (w_VUV= 2wR− wT) in krypton has been investigated. The frequency wR (λR …

A review of experimental studies of the measurement of the photoionization cross-section for
the excited states of the alkali atoms, alkaline earth atoms, and rare-gas atoms is presented …

We present a very sensitive and scalable method to measure the population of highly
excited Rydberg states in a thermal vapor cell of rubidium atoms. We detect the Rydberg …

Lithium isotope separation has been achieved employing the two-step photoionization
technique along with a narrow band dye laser in conjunction with a time of flight mass …

Abstract Development of resonance ionization spectroscopy (RIS) has made the concept of
single-atom counting, whether radioactive or stable, practical for most elements of the …

We investigate the properties of a trace-gas sensing scheme based on Rydberg excitations
at the example of an idealized model system. Rydberg states in thermal rubidium (Rb) are …

The photoionization cross section from the 3s3p 1 P 1 excited state has been measured in
the energy region from the first ionization threshold up to 1.4 eV excess energy using a two …

The construction and the use of a single mode semiconductor diode laser spectrometer
which can be tuned electronically controlled by temperature as well as by current is …
