Permanent dipole moment of LiCs in the ground state

Permanent dipole moment of LiCs in the ground state

Recently we demonstrated the formation of ultracold polar LiCs molecules in deeply bound levels of the X{sup 1}{Sigma}{sup +} ground state, including the rovibrational ground state [J. Deiglmayr et al., Phys. Rev. Lett. 101, 133004 (2008)]. Here we report on an experimental determination of the perm...

Description
Summary:Recently we demonstrated the formation of ultracold polar LiCs molecules in deeply bound levels of the X{sup 1}{Sigma}{sup +} ground state, including the rovibrational ground state [J. Deiglmayr et al., Phys. Rev. Lett. 101, 133004 (2008)]. Here we report on an experimental determination of the permanent electric dipole moment of deeply bound LiCs molecules. For X{sup 1}{Sigma}{sup +}, v{sup ''}=2, and v{sup ''}=3 we measure values of {mu}=5.5(2) D and 5.3(2) D, respectively.
