Photon-H$_2$ cross sections and hydrogen plasma equations of state

ORAL

Abstract

Studies of molecular plasmas both in local thermodynamic equilibrium (LTE) and non-LTE require state-resolved (electronic, vibrational and rotationally resolved) transition cross sections or rate coefficients to calculate populations (for non-LTE plasmas), opacities and emissivities. Here we present state-resolved results of photodissociation and radiative association of H$_2$ and its isotopologues (D$_2$, T$_2$, HD, HT, and DT), and preliminary results of low-temperature hydrogen plasma equations of state and opacities.
