Using a nonselective broadband detection scheme we discovered an efficient mechanism of formation of ultracold Cs(2) molecules in deeply bound vibrational levels (v=1-9) of their electronic ground state X (1)Sigma(+)(g). They are formed by a one-photon photoassociation of ultracold cesium atoms in a manifold of excited electronic states, followed by a two-step spontaneous emission cascade. This process creates about 10(5)-10(6) molecules per second. This detection scheme is an advancement compare to previous ones and could be generalized to other molecular species for the systematic investigation of cold molecule formation mechanisms.

Abstract

Using a nonselective broadband detection scheme we discovered an efficient mechanism of formation of ultracold Cs(2) molecules in deeply bound vibrational levels (v=1-9) of their electronic ground state X (1)Sigma(+)(g). They are formed by a one-photon photoassociation of ultracold cesium atoms in a manifold of excited electronic states, followed by a two-step spontaneous emission cascade. This process creates about 10(5)-10(6) molecules per second. This detection scheme is an advancement compare to previous ones and could be generalized to other molecular species for the systematic investigation of cold molecule formation mechanisms.
