Difference between Radioactivation and protonInelastic

Physics Processes, Models and Cross Sections
1

Hello,

I work on 100Mo(p, x)Y nuclear reactions modeling on a cyclotron solid target. I’m trying to investigate produced isotopes and processes created them. In the attached output file I found two different processes which produced different states of metastable 99mTc. The first state is Tc99[142.683] made by protonInelastic process, and the second is Tc99[140.511] which origins from Radioactivation process. So, the question is what is the different between these processes and states produced by them? I thought the Radioactivation is radioactive decay, but there is another RadioactiveDecay process purposed for that.

Sincerely, Ihor

Both are (p, 2n). The first is probably (p, 2n) and is a “direct reaction” state for the compound nucleus. The second is from an equilibriated 99Mo that beta decays to 99Tc. Because of the extra kinetic energy, this beta decay may be very fast.
