Radiative association

Published: 15 October 2015

Radiative association is one of several processes which contribute to the production of molecules in different astrophysical environments such as interstellar clouds and protoplanetary disks. It is especially important in dust-poor regions of space where reactions due to ternary collisions are rare. Experimental studies of the process in the laboratory are quite complicated, which makes theoretical investigations desirable.

In our group the main focus is made on the role of quantum effects (e.g. scattering resonances and non-adiabatic couplings) in radiative association. For the solution of dynamical problems we employ time-independent quantum methods, but also trajectory based classical methods. Radiative association of a number of neutral diatomic molecules has been investigated (CN, CO, SiN, SiP, HF, HD, and NaK). At present we are looking towards ionic systems as well as polyatomics.
