| Outline of Final Research Achievements |
A rovibrationally resolved collisional-radiative model of molecular hydrogen that includes 4,133 rovibrational levels for electronic states whose united atom principal quantum number is below six is developed. The population distribution of the rovibrational in the electronic ground state in a fusion demo detached divertor plasma is investigated by solving the model time-dependently with an initial 300 K Boltzmann distribution. The effective reaction rate coefficients of molecular assisted recombination and of other processes in which atomic hydrogen is produced are calculated using the obtained time-dependent population distribution.
A neutral transport code including the rovibrational excitation of molecule hydrogen induced by atomic hydrogen, and a collisional-radiative model of atomic hydrogen with the levels specified by the principal and azimuthal quantum numbers are also developed.
