| Abstract | The pseudo-closed transition with enough large Frank-Condon factor (FCF) is a necessary condition for direct laser cooling molecules, which means that only a few molecules with the appropriate ground and excited electronic states can be considered as potential candidates. The electronic and spectroscopic properties of five Omega states are evaluated for the PbH, PoH, BiH+, and AtH+ molecules based on the four-component full relativistic calculations with all-electron basis sets, by which we construct optical schemes for these molecules by using the X-1(2)Pi(1/2) (nu'') <-> X-2(2)Pi(3/2) (nu') transitions for PbH and BiH+ or the X-1(2)Pi(3/2) (nu'') <-> X-2(2)Pi(1/2) (nu') ones for PoH and AtH+. The built schemes can provide 10(4) similar to 10(5) scattering phonons with three or five pumping lasers. Moreover, the Doppler/recoil temperatures are 2.08 x 10(-3)/0.04, 2.91 x 10(-3)/0.11, 7.48 x 10(-3)/0.08 and 0.01/0.18 mu K, respectively, which means that the temperature of the order of nanokelvin for the PbH and PoH and microkelvin for the BiH+ and AtH+ molecules may be cooled based on the present optical schemes. |
