Z. Pavlovic, H. R. Sadeghpour, R. Cote, B. O. Roos

摘要:

本文计算了铬-铷杂原子分子52 Cr-87 Rb的Born-Oppenheimer势能曲线,以及基态Cr和Rb原子相互作用的长程色散系数。我们计算的范德华系数(C6=1770 a.u.)预期误差为3%。处于平衡分离的基态6 σ +分子具有de(Re=3.34 A)= 2.90 D的永久电偶极矩。我们研究了Cr和Rb原子的超精细和偶极碰撞,发现弹性和非弹性截面比为100-1000。

英文摘要:

We report calculations of Born-Oppenheimer potential energy curves of the chromium-rubidium heteronuclear molecule 52Cr-87Rb, and the long-range dispersion coefficient for the interaction between ground state Cr and Rb atoms. Our calculated van der Waals coefficient (C6=1770 a.u.) has an expected error of 3%. The ground state 6Sigma+ molecule at its equilibrium separation has a permanent electric dipole moment of de (Re=3.34 A) = 2.90 D. We investigate the hyperfine and dipolar collisions between trapped Cr and Rb atoms, finding elastic to inelastic cross section ratio of 100-1000.
