How can I activate physical processes for electrons?

Dear FLuka
how i can to active physical prossece for electrons ?

Hallo, they are already active - above the requested threshold - by default (e.g. with the recommended DEFAULTS card asking for PRECISIO settings). The only exception is for electro-nuclear reactions requiring, when they are actually relevant, a dedicated PHOTONUC card with ELECTNUC.

thank u soo much
