Hi Elton, all -

Another contender to explain the C14 spikes.
That can be added to the existing four:
1)hole in upper atmosphere,
2)interuption of ocean currents,
3)coincident incresase in extra-solar neutrons, and
4)neutron release in impact process.

For the comets, I could see how there might be C14.
But does the solar wind or interspace contain C14?

Two questions on my mind. First do irons contain C14?
Second, does anyone have a fine scale chart of real
C14 production from about 3,114 BCE on?

good hunting all,
E.P. Grondine
