Dear Mikhail and Anton,

In your valuable response to Felicia's problem, I have just a query about
the output spectrum you obtained with the help of DETECT card. The spectrum
that we observe experimentally by bombarding 661.7 keV photons on NaI
detector always comprises of Gaussian spread in full energy peak. How we
can obtain the exact spectrum showing Gaussian spread. Could you please
share the file using DETECT card for obtaining the results that you have
discussed in earlier e-mails.

Thanks & Regards,
A. Sharma
