Re: peaks in the pulse height spectrum

Dear mary,
   Thanks for your return.
    There is still some phenomena bothering me. I am afraid that peaks appearance not because of recoil kinematics. The monte carlo simulation result should be close to the experimental spectrum. I am always doing the experiment with TEPC. And I could not explain the peaks. I have read papers published by Dr.Sofia Rollet in which the TEPC spectrum simulated and there were no mono-energy peaks. I tried to contact her but not successful. She once sent email to the fluka discuss. She may have other advice.
Best regards,

Hai Weihua,
Applying a spreading function would no longer be Monte Carlo. I am not
sure how meaningful it would be to post-process that way. Otherwise, there
is of course a standard palette of blurring functions (the most common one
being Gaussian) one can technically pull off-the-shelve in Signal
Processing. Technically one can, but consider the validity, and consider
how are you going to treat different radiation conditions (energy at the
time of collision, local composition, the events upstream and downstream,
:) mary
