Production cross section of 67Ga and 68Ga from interaction of Li7 beam on Cu target

Scoring

  1. Please note that 67Ga and 67Ge are not the same nucleus.
    The FLUKA result for the latter is as follows:

67Ge

exceeding at most by a factor 2 the data you report.

  1. Not sure what you mean with total response (obviously it’s not the total response of your USRYIELD, which was limited to 67Ga). By definition of reaction cross section, it includes all reaction channels.

  2. No. Since your target is made of natural copper (as in reality), the resulting cross section is the weighted average of the two.

  3. What is written in the manual (excluding low energy neutron reactions).
