Prompt and delayed gamma time window in simualation

Dear Users and Developers,

I would like to differentiate the Prompt gamma and delayed gamma in 20 MeV neutron-induced reactions on various targets. Currently, I am using the global time to differentiate these two contributions. For example, I am tagging the detected gammas considering from the prompt contirbution when global time is within few (1-2) micro-seconds (us). SImilarly the delayed ones, when the global time of their registration is greater than 10 microseconds. I would like to know if I am using the proper approach or there is some dedicated procedure in Geant4 to do so.

Thank you in advance.

With best regards,

Hello arjun,
I have same problem now. I would like to know which method can solve it or do you have some new method now?

I would be grateful for your help
