This is an[[br]] important mechanism for forming H,,2,, molecules which act as a coolant [[br]]in primordial clouds. This cooling effect is necessary in the formation of the first stars. Knowing[[br]] these rates would allow us to accurately model the formation[[br]]of the first stars and see if protogalactic halos cooled down before they[[br]] would have likely collided with another halo. 6 6 [[br]] 7 [[Image(https://docs.astro.columbia.edu/attachment/wiki/SavinGroup/MergedBeams/First Star.png?format=raw, 50%, right)]]` Abel et al, Science 2002` 7 8 [[br]] 8 9 == Experimental setup ==
