Steven :

You have mentioned two of the indicators, i.e. the mean number of
authors per paper, and the percentage of multiple-authored papers (this
is just the complement of the percentage of single authored papers).
There is a third one, called the collaborative coefficient, which is
more sensitive than the other two.   See the following article for details :

Ajiferuke, I. , Burrell, Q. & Tague, J. (1998). Collaborative
coefficient : A single measure of the degree of collaboration in
research. Scientometrics, 14(5-6), 421-433.

Best wishes,
