Dear Maxim Yurievich,
I tried to fix all the shortcomings. About the momentum distribution, I wrote that, following from the fact that gravitino is a fermion, its gas should be described by Fermi-Dirac statistics.

and Gravitino gas should be described by the Boltzmann equation.

Dear Aisen,
I asked you to calculate the gravitino momentum distribution, coming from freeze in processes!
It has nothing to do with thermal equilibrium distribution!

Thank you.
Please correct numeration of references marked yellow in the attached file.
I also don't see an answer to the question on gravitino momentum distribution in freeze in mechanism.
If you don't obtain it now, you'll have to do it at exam, since it will be an additional question
With the best regards

Dear, Maxim Yuryevich.
I tried to derive something, although I did not take the integral

Dear Aisen,
At least you made an attempt.
To pretend on excellent mark I recommend you to choose and additional question together with ticket and
prepare answer to it together with answers to questions of ticket
With the best regards
