    4 We are measuring rate coefficients of the reaction H^^-^^ + H = H,,2,,. This is an important mechanism for forming H,,2,, molecules which act as a coolant in primordial clouds.[[br]] This cooling effect is necessary in the formation of the first stars. Knowing[[br]] these rates would allow us to accurately model the formation of the first stars and see if protogalactic halos cooled down before they would have likely collided with another halo.
