Chapter and Conference Paper
The Kascade-Grande experiment
The KASCADE-Grande experiment measures extensive air showers induced by primary cosmic rays in the energy range 1014 – 1018 eV. The major motivation for KASCADE-Grande is the investigation of the so called ”knee”...

A re-evaluation of isotope shift constants
The field isotope shift constantC unif for a uniform nuclear charge distribution has been re-evaluated fors-electrons for elements with 10≦Z≦ 95. A table is given which permitsC unif to be found for any isotope p...

Improved calculation of field isotope shift constants for optical spectral lines
Following the approach of previous investigations improved formulae for the field isotope shift constantC unif of optical spectral lines have been derived assuming a uniform nuclear charge distribution. From thes...

Isotope shift and hyperfine structure of the transition5d6s 2 2 D 3/2-5d6s6p 4 F 3/2 of Lu175 and Lu176
Using a tunable single mode dye laser the isotope shift of the 573.7 nm-line between the isotopes Lu175 and Lu176 has been determined to be IS(176−175, 573.7 nm)=−394(5) MHz yielding a change of mean square nucle...

Investigation of hyperfine structure and isotope shift of the 605.5 nm-line of Lu176 by laser spectroscopy
Using a tunable single mode dye laser the hyperfine structure of the transition 5d6s 2 2 D 5/2 — 5d6s6p 4 F 5/2 has been investigated for the Lu-isotopes Lu175 and Lu176. From our measurements the following value...

Level-crossing-Untersuchung der Hyperfeinstruktur des angeregten 32 P 3/2- und 42 P 3/2-Zustands von Na23
The hyperfine structure of the excited 32 P 3/2- and 42 P 3/2-state of Na23 has been investigated in a level-crossing-experiment by means of a detailed analysis of the dependence of the scattered resonance light ...
