The scarcity of accurate and comprehensive data sets for rovibrational (RV) inelastic cross sections and rate coefficients has been a serious limitation for the development of astrophysical models. In particular, the investigation of cooling processes, molecular emission, and non-equilibrium effects in molecular regions and gaseous nebulae requires H, He, and H2 collisional excitation data of the dominant molecular species such as H_2, HD, and CO. These collisional processes play important roles in a variety of environments from starburst galaxies, to the formation of the first stars, to the study of high-redshift damped Lyα systems, to molecular clouds in our own galaxy. The present work reports our progress on quantum-mechanical, close-coupled cross sections calculations for the collisional excitation of H2 by He impact. The results are compared to previous calculations, limited primarily to RV transitions between low-lying states, and to available experimental data.
