# changing height\depth of sub- and superscripts

I *think* I've seen this discussed in an earlier post, but despite my

better efforts, I can't seem to track it down.

I'm interested in techniques/options for changing the height (for

superscripts) or depth (for subscripts) from the LaTeX defaults - in

other words, change (overrride) the default vertical spacing rules for

sub- and superscripts. I ask because quite often, my students make

mistakes on assignments by confusing what should have been subscripts

as separate variables in an equation.

For example, $\rho\gamma_{PH}$. The PH product should be a subscript

for \gamma, but in \cm font, if you're not paying attention when

reading, it looks a lot like rho * gamma* PH. In other words, the

subscript depth for {PH} isn't 'deep' enough for the reader to

unambiguously see that the {PH} is a subscript. THis would be solved,

I think, if I could make the subscript a bit deeper (same being true

in reverse for superscripts).

Suggestions? Pointers to the obvious?

Thanks in advance...
