The C14 calibration data only goes back 24,000 years, and there have been no
confirmed significant impacts during that time, and not even any well dated
minor impacts. So how can spikes in the calibration curve be linked to
impacts?
Even given a large impact (a big given), there are plausible explanations
for how this would affect C14 concentrations; far more plausible than the
very unlikely production of neutrons.

Take a look at the INTCAL98 14C calibration chart. Major spikes appear to
map to impacts.
