Study of coupled states for the ( 4 s 2 ) 1 S + ( 4 s 4 p ) 3 P asymptote of Ca

Pressure dependence of the Mg 3 s 4 s 3 S 1 → 3 s 3 p 3 P 0 , 1 , 2 transition in superfluid 4

The pressure shifts of the 3s4sS1 → 3s3p P0,1,2 transition of magnesium atoms immersed in superfluid helium have been measured at (1.3± 0.1 )K between saturated vapour pressure and 24 bar. The wavelength is blue shifted linearly by (0.07 ± 0.01) nm bar . This value can be satisfactorily described in the framework of the standard bubble model.

High - temperature calcium vapor cell for spectroscopy on the 4 s 2 1 S 0 – 4 s 4 p 3 P 1 intercombination line

We have demonstrated a high-temperature vapor cell for absorption spectroscopy on the Ca intercombination line. The cell uses a dual-chamber design to achieve the high temperatures necessary for an optically dense vapor while avoiding the necessity of high-temperature vacuum valves and glass-to-metal seals. We have observed over 50% absorption in a single pass through the cell. Although pressur...

Quantum Sl(3,c)’s: the Missing Case

We study the only missing case in the classification of quantum SL(3, C)’s undertaken in our paper [J. of Algebra 213 (1999), 721–756], thereby completing this classification.
