Bob Leif points out that the diodes used for forward scatter detection
in most commercial systems are insensitive to 325 nm UV. Good point.
I wasn't thinking about that because the original query reported getting
some signals. However, the lousy FS signals I got at 325 nm with a
multimode HeCd laser were obtained using a PMT as a detector, which
means lack of detector sensitivity isn't the only obstacle.
