Dear Vittorio and Alfredo,
thank you for your reply.
_at_Alfredo: As I was writing to Vittorio in another discussion (Neutron Yield
from Be target), simulating the neutron production from proton on Be I
found results much closer to the experimental results without the
COALESCEnce card (7% with coalescence, 9% without, 10% experimental
results).
(I apologize for the multiple e-mail).
From what you've written, however, I understand that the coalescence should
be activated in this process, is this correct? Or there is a reason why for
the neutron yield it's better not to activate the card?
Thank you very much for your help
Emilio Ciuffoli
