Model of Early Universe with H+2

Tae Song Lee, University of Nevada, Las Vegas


The aim of this thesis is to improve existing models of the Early Universe by adding vibrationally resolved reactions to a standard model. Stancil, Lepp, and Dalgarno (1996, 1998) have developed a standard chemical model for molecules in the Early Universe. Galli and Palla (1998) have shown that vibrational excitation may be important in this model by forcing the vibrational level of H+2 to be either v=0 or v=9. I studied a consistent model for the vibrational levels including level dependent formation and destruction as well as transition between the levels.
