Abstract

Several different experiments involving the making of cold and ultracold molecules are performed and proposed. Ultracold cesium molecules are produced in a magneto-optical trap (MOT) by photoassociation near the 6P _j, 7P_j, 9S _1/2, 6D_3/2, 7D_3/2 and doubly excited asymptotes. Perturbation effects related to resonant channel coupling were observed in photoassociation spectra below the 6 P_1/2 asymptote. Such effects are used to illustrate a ground state ultracold molecule formation mechanism, which can also be formed in one step photoassociation to the double minimum 3¹S⁺m state. In addition, a new technique of making cold molecules of cesium hydride is proposed, using a cold hydrogen beam source and a cesium MOT. Due to reaction energetics, the formed CsH molecules should be in their lowest rovibrational states. ^
