We have developed a new vapor cell Magneto optical trap to investigate
heteronuclear cold collisions. At the present we have concluded the
investigation of exoergic collisions with the following mixtures :
Na/Rb, K/Rb, Na/K and Rb/Cs. Laser intensity dependence of rate
coefficients were investigated.
