[Olympus] 2pi production.

[Belostotski, Stanislav]

Dear Michael,
In line of our yesterday discussion, find please in the attached file =

kinematics for one and two pion production thresholds. You are right, =

the 2pi border is not too close to the elastic peak, but our momentum =

resolution ( I mean 12 deg.) is very poor so due to smearing it might be =

also some contribution from 2pi.
I have also attached Gramolin's calculations. Note that this is the case =

of  essentially smaller primary energy.Somewhat surprising is that the =

radiation tail in Gramolin's picture looks much less pronounced as being =

presented by Brian. I understand of course, different kinematics, =

but...I wonder if our pion production generator was cross checked by =

comparing with elrctro/photo pion production data.
With best regards StanB
