Hi Ralf,
You might remember me -- I think we have met once or twice -- as someone who
has a crossed molecular beams apparatus, which is a copy of the "35-inch
machine" that was originally built at Berkeley. I have used the machine
largely for photochemistry and for beam-surface scattering, but I have
recently been doing some crossed-beams experiments involving O(3P) reactions
with alkanes at high collision energies (1.5 - 7 eV). I believe that you
have used the original machine extensively, and I was wondering if you had
an analysis program that you used for the crossed-beams experiments. We
obtained a program from Xueming Yang, but we have found it difficult to
implement for our analysis, especially since we only have an executable code
(the source code was apparently lost). We also obtained the program,
GMTHRASH, from Arthur Suits, but for some reason, the program did not work
and one of my students spent a long time getting it to work (or so I
thought). But then the student left before passing down the knowledge to
anyone else. Now, I have a student who is trying to do some analysis, but I
am skeptical of the results we are obtaining. The optimization part of the
program gives results that make no sense, and it has also been difficult to
implement a point form for the angular distribution. I thought that you
have alot of experience on the same machine we have and that perhaps you
have a "tried-and-true" analysis program that we could put to use
immediately. We could probably get the program we have to work eventually,
but it would be nice not to have to "reinvent the wheel." If you have a
reliable analysis program that you could pass on to us, I would appreciate
it very much.
Thanks,
Tim
