MOL-D: A Collisional Database and Web Service within the Virtual Atomic and Molecular Data Center

摘要

MOL-D database is a collection of cross-sections and rate coefficients forspecific collisional processes and a web service within the Serbian VirtualObservatory (SerVO) and the Virtual Atomic and Molecular Data Center (VAMDC).This database contains photo-dissociation cross-sections for the individualro-vibrational states of the diatomic molecular ions and rate coefficients forthe atom-Rydberg atom chemi-ionization and inverse electron-ion-atomchemi-recombination processes. At the moment it contains data forphotodissociation cross-sections of hydrogen H2+ and helium He2+ molecular ionsand the corresponding averaged thermal photodissociation cross-sections. Thero-vibrational energy states and the corresponding dipole matrix elements areprovided as well. Hydrogen and helium molecular ion data are important forcalculation of solar and stellar atmosphere models and for radiative transport,as well as for kinetics of other astrophysical and laboratory plasma (i.e.early Universe).
