A PhD thesis for the student (Abdul Sattar Khalil Maarouf) was discussed in the Department of Physics - College of Science - University of Anbar on Wednesday 30/6/2021 at Jaber bin Hayyan Hall in the College of Science for his tagged thesis: (The Angular Distribution Spectra Estimations for some N-N Pre-equilibrium Nuclear Reactions using Feshbach - Kerman - Koonin (FKK) model)

The aim of the study estimate the particle spectrum and the angular distribution for some N-N pre-equilibrium nuclear reactions (n'n) (n'p)(n'D)(n'T)(n'3He) and (n'4He) by adopting FKK model in the Kalbach systematics applying to particles emitted during direct 'inelastic and knockout reactions involving primary and secondary emission in the frame of exciton model. Besides the equilibrium partical evaporation.
