Re: Question about low energy neutron propagation

Dear Ms. Harris,

after sending you my previous answer, I decided to double-check the
situation of the availability of gamma generation information for the
three elements you mentioned, because the lack of gamma generation in Ag
looked a bit surprising to me.
In fact, there was a mistake in the manual: the "N" should have been a
"Y" in the line concerning silver.
For what concerns Helium, the lack of gamma is real: no gamma can physically
be generated in capture of neutrons with energy < 20 MeV.

Sorry for the mistake
