First charge radii measurements of three very light calcium isotopes
2019/02/12
Isotope shift measurements on three light calcium isotopes (Ca-36 to Ca-39) have been published in Nature Physics . The measurements were performed at NSCL/MSU and LaserSpHERe has contributed by the development of the fluorescence detection region. The publication is announced in a Press Release by TU Darmstadt ( idw , in German) entitled „Rätselhafte Größe extrem leichter Calciumisotope".

First spectroscopic Results from COALA are published
2019/01/18
Our measurements of transition frequencies and isotope shifts of all stable barium isotopes in the D1 and D2 transitions have been published in Physical Review A . To our knowledge, these are the most precise collinear measurements performed so far. Our result for the transition frequency of Ba-138 is even slightly more accurate than a recent measurement on laser-cooled ions in a Paul trap.
