Right angle scatter with UV laser line?

We don't do that much UV on our flow but I've just across what seems to
be a problem and I knew someone out there could help.

Do you not get right angle light scatter (or very little of it) when
using the UV line? I was just setting up for an experiment in which we
will be using UV on our FACS 440. For alignment, I was using some old
Polyscience beads
(about 5 micron dia.) that still fluoresce and I didn't see much side
scatter.
Should I? Will it be different with cells, i.e., will I see SS with cells
even though I don't see it with these beads? If not, is it a property of
the laser line or the PMT?

Thanks for any answers.

Ray
