Properties of metastable alkaline-earth-metal atoms calculated using an accurate effective core potential
Robin Santra, Kevin V. Christ, Chris H. Greene
The first three electronically excited states in the alkaline-earth-metal atoms magnesium, calcium, and strontium comprise the (nsnp) triplet P^o_J (J=0,1,2) fine-structure manifol…
Multichannel cold collisions between metastable Sr atoms
Viatcheslav Kokoouline, Robin Santra, Chris H. Greene
We present a multichannel scattering calculation of elastic and inelastic cold collisions between two low-field seeking, metastable ^{88}Sr [(5s5p) ^3P_2] atoms in the presence of…
Tensorial analysis of the long-range interaction between metastable alkaline-earth atoms
Robin Santra, Chris H. Greene
Alkaline-earth atoms in their lowest triplet P_2 state are exceptionally long-lived and can be trapped magnetically. The nonspherical atomic structure leads to anisotropic long-ran…
