keyword=ugh. 80 deg cross sectionBelow is the e_miss peak for run 2062.
Using these counts, scaling to total number of T5's in the file,
doing all the appropriate scalings, I get a cross section of 3.6 x 10^-6 ub/sr
Joe's program printed a cross section of 1.76 x 10^-5 ub/sr.
By assuming we lose 60% of the target length since the proton spec
was close to 90 deg I can get closer (6 x 10^-6) and assuming 0.7
for radiation tail I get 7.5e-6 but still more than a factor of two off.
.
ai. perhaps it is this problem of triggers coming thru as T3 when they
are really T5. I will try computing from e- arm only.
.
This is a dismal failure. There are almost no electron singles as far as I
can tell. Perhaps I need to reset the file for 1H(e,e')
.
Fig below is kin-corrected delta spectrum in e arm, demanding NO
h-arm good track. There are fewer events here, when in fact there should
be more events here (no limitation on h-arm from target length).
.
Given this analysis, we should have something like 7000 events in
the elastic peak.
