Resonance ionization spectroscopy

Collinear resonance ionization spectroscopy of neutron-deficient francium isotopes.

The magnetic moments and isotope shifts of the neutron-deficient francium isotopes (202-205)Fr were measured at ISOLDE-CERN with use of collinear resonance ionization spectroscopy. A production-to-detection efficiency of 1% was measured for (202)Fr. The background from nonresonant and collisional ionization was maintained below one ion in 10(5) beam particles. Through a comparison of the measur...

Resonance ionization spectroscopy on Yb and No at SHIP

For the investigation of the completely unknown atomic level structure of the element nobelium a novel experimental procedure has been developed. It is based on Radiation Detected Resonance Ionization Spectroscopy (RADRIS) which had to be improved and modified to accommodate the prerequisites at SHIP. It can be applied to elements like nobelium produced at rates of a few ions per second. The io...

Zero kinetic energy-pulsed field ionization and resonance enhanced multiphoton ionization photoelectron spectroscopy: Ionization dynamics of Rydberg states in HBr

The results of rotationally resolved resonance enhanced multiphoton ionization photoelectron spectroscopy and zero kinetic energy-pulsed field ionization studies on HBr via various rotational levels of the F D2 and f D2 Rydberg states are reported. These studies lead to an accurate determination of the lowest ionization threshold as 94 098.961 cm. Observed rotational and spin–orbit branching ra...
