Solar Sails driven by Photons or Particles?

Hi,
I have a discussion in a german newsgroup de.sci.raumfahrt :
Message-ID: .com

The question is, what makes more pressure on the solarsails, the Photons or
the Particles like Ions and Electrons?

Wikipedia etc. don't give us the clue.

Any help appreciated

Photons. You should monitor sci.space.* where this has IIRC been dealt
with.

Sorry I my providers newsserver doesnt have sci.space did you mean

know a public newsserver that holds sci.space ?

He said sci.space.*

The asterisk is the standard wildcard meaning "any group starting with
sci.space."
