Multiple Time Scales in the Microwave Ionization of Rydberg Atoms
1995
We investigate the time dependence of the ionization probability of Rydberg atoms driven by microwave fields, both numerically and experimentally. Our exact quantum results provide evidence for an algebraic decay law on suitably chosen time scales, a phenomenon that is considered to be the signature of nonhyperbolic scattering in unbounded classically chaotic motion.
Die relative Isotopenlage des Os186
1962
Using three different samples of Os192, Os190 and Os186 enriched to 98.68%, 95.46%, and 61.27%, respectively, the isotopic shiftsΔν(Os192−Os190) andΔν(Os192−Os186) have been measured in four Os I-lines with a recording Fabry-Perot spectrometer. The relative isotopic position of Os186 has been found to be $$\frac{{\Delta \nu (Os^{192} - Os^{186} )}}{{\Delta \nu (Os^{192} - Os^{190} )}} = 3.52 \pm 0.03.$$
Das Vorzeichen der Hyperfeinstruktur-Aufspaltung des 3d 5 4s 2 6 S 5/2-Grundzustandes des Mn55
1962
Using a double Fabry-Perot interferometer and an atomic-beam light source, the sign of the hyperfine-structure splitting of the 3d 5 4s 2 6 S 5/2 ground state of Mn55 has been determined to be negative. The absolute value of the splitting previously has been measured byWoodgate andMartin.
