[Nuclear] feedback to Nikolai Pivnyuk

[Nikolai Pivnyuk]

Eugene,
thanks a lot for the reference to γn → π-p. I guess it might be very
interesting to look at g13 data form the point of view of the nuclear
physics, just in a similar way how we proceed in g10.

The analysis of g10  gd->pi-p,p_s is essentially a NUCLEAR analysis, I
mean the goal is to understand the mechanism of the pion production off
deuterium, through the analysis of the correlations between different
kinematical variables (Eg, t_pi, t_p_fast, p_slow_p, cosTHETA_s, THEAT_TY,
etc) in the 3-BODY FINAL STATE of the reaction.

Thanks a lot Eugene,
Thanks a lot Mike.

Nikolai
