Hello, I would like to know if there is a digital site to obtain the collision cross section data (Electron Impact Reaction), used in the plasma module.

thanks.

Hello Fabian,

The Plasma Module's User's Guide, version 5.5, gives two references for cross section data, see pages 32-33.

Best regards,

Jeff

Hello, I have another question, how could I calculate the statistical weight that comsol asks me for the excitation reactions? thanks

Dear Fabian, These statistical ratio of the final state to initial state related to quantum numbers/states, For atomic species: g=2J+1 where J is the total electronic angular momentum
