The narrowband light from a scannable, single-mode dye laser influences the electrical properties of gas discharges. The variation in these properties as the laser wavelength λ is scanned yields the optogalvanic spectrum of the discharge (i.e....
I met Claudio in 1989 when I was starting the last year of my physics bachelor’s degree [...]
Magnesium monofluoride is a polar molecule amenable to laser cooling which has caused renewed interest in its spectroscopy. In this work, we consider the case of three low-lying electronic excitations, namely X2Σ+→A2Π, X2Σ+→B...
A collisional radiative model for Kr III in the ultraviolet regime is developed. For this purpose, atomic parameters for 4s24p4, 4s4p5, 4s24p3nl, and 4s24p35d configurations with n ranging from 5 to 7 and l=s,p, using the multiconfiguration Dirac&nda...
We review our group’s most significant results concerning the collision of positrons and electrons with small molecules. Total and triple differential cross sections for the ionization of these targets were calculated in the distorted wave Born...
