Dear Xavier, thanks for your response. Yes, indeed I have tried to contact the authors, but perhaps they can't receive my mails. I have tried scaling sigma alone to 0.9 or 0.965 (which would correspond to a 10% reduction of radius or volume respectively). Since some special particles scale epsilon along with sigma, I also tried this, but with no success. Cheers, Cesar
