We investigate the dynamics of a continuous atom laser based on the merging of independently formed atomic condensates. In a first attempt to understand the dynamics of the system, we consider two independent elongated Bose-Einstein condensates which approach each other and focus on intermediate inter-trap distances so that a two-mode model is well justified. In the framework of a mean-field theory, we discuss the quasi-steady-state population of the traps as well as the energy distribution of the outcoupled atoms.

The electrochemical behavior of a complex of cobalt with dimethylglyoxime Co(DMG) 2 (ç 2 é) 2 is studied by cyclic voltametry. Peaks corresponding to redox transitions ëÓ( III )/ëÓ( II ) and ëÓ( II )/ëÓ( I ) are observed in the potential region 0.4 to -1.8 V (Ag/AgCl). The product of reduction of the initial complex interacts with carbon dioxide to form a stable compound, probably an intermediate product of electrocatalytic reduction of ëé 2 to CO in the presence of N 4 -macrocyclic complexes of cobalt.
