Significant Difference

In this paper a special effect of aluminium and nickel on the spectral lines of alkaline-earth metals being present in low concentration was studied. During the study a sharp difference could be obtained in the behaviour of atomic and ionic lines, therefore among the lines investigated both atomic and ionic ones were included. The effect of Ni and Al was investigated in a wide concentration range in case of Be, Mg, Ca and Sr. In case of each of the four alkaline-earth element a significant difference in the depression of the signal could be observed with increasing Al or Ni concentration among atomic and ion lines.

Laser Cooling And Trapping

Obtaining ultracold alkaline earth(-like) atoms in space encounters the problem of performing narrow-line laser cooling in microgravity environments ( μ -gEs). This paper reports an analysis of the magneto-optical trap (MOT) based on the narrow-line transition in 88 Sr, while paying special attention to the role of the gravity. This analysis suggests the MOTs based on narrow-line transitions cannot be cold and dense enough in a μ -gE. We thus propose a strategy: that one can use a dual-frequency MOT to realize a low-temperature, high density, and high transfer efficiency, narrow-line red MOT in μ -gEs.
