[G14_run] [EXTERNAL] Re: Your presentation at NSTAR 2022

[Annalisa D'Angelo]

Dera Andrey,

thank you for promt reply and for your slides! I have just uploaded them 
on the NSTAR 2022 web site.

We are planning to obtain results for the gamma n-> pi+pi-n single and 
duouble polarizationa symmetry first, because they are easier to extract 
from the data.

We may consider to determine the cross section, should you think it 
would be beneficial to the understanding of the reaction dynamics.

All the best

Annalisa
