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…
Multiplet Structure of Feshbach Resonances in non-zero partial waves
C. Ticknor, C. A. Regal, D. S. Jin +1
We report a unique feature of magnetic field Feshbach resonances in which atoms collide with non-zero orbital angular momentum. P-wave () Feshbach resonances are split into tw…
Field-linked States of Ultracold Polar Molecules
A. V. Avdeenkov, D. C. E. Bortolotti, J. L. Bohn
We explore the character of a novel set of ``field-linked'' states that were predicted in [A. V. Avdeenkov and J. L. Bohn, Phys. Rev. Lett. 90, 043006 (2003)]. These states exist a…
Wave Mechanics of a Two Wire Atomic Beamsplitter
Daniele C. E. Bortolotti, John L. Bohn
We consider the problem of an atomic beam propagating quantum mechanically through an atom beam splitter. Casting the problem in an adiabatic representation (in the spirit of the B…
Phase Space Manipulation of Cold Free Radical OH Molecules
J. R. Bochinski, Eric R. Hudson, H. J. Lewandowski +2
We report bunching, slowing, and acceleration of a supersonically cooled beam of diatomic hydroxyl radicals (OH). \textit{In situ} observation of laser-induced fluorescence along t…
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…
