英文摘要	using fitted model potential curves of the ground and lowest three excited states yielded by the relativistic kramers-restricted multireference configuration interactionmethod with 19 electrons correlated, we theoretically investigate the rovibrational properties including the number of vibrational state and diagonally distributed franck-condon factors for a (rbsr)-rb-87-sr-84 molecule. benefiting from a turning point at about v ' = 20 for the franck-condon factors between the ground state and spin-orbit 2(omega = 1/2) excited state, we choose vertical bar 2(omega = 1/2), v ' = 21, j ' = 1 > as the intermediate state in the three-level model to theoretically analyze the possibility of performing stimulated raman adiabatic passage to transfer weakly bound rbsr molecules to the rovibrational ground state. with 1550 nm pump laser (2 w/cm(2)) and 1342 nm dump laser (10 mw/cm(2)) employed and appropriate settings of pulse time length (about 300 mu s), we have formalistically achieved a round-trip transfer efficiency of 60%, namely 77% for one-way transfer. the results demonstrate the possibility of producing polar (rbsr)-rb-87-sr-84 molecules efficiently in a submicrokelvin regime, and further provide promising directions for future theoretical and experimental studies on alkali-alkaline(rare)-earth dimers.
