The production of photons from heavy-ion collisions at intermediate energies is studied in the model based on the Boltzmann-Uehling-Uhlenbeck equation. Taking into account photon production from nucleon-nucleon collisions, the theoretical results are in reasonable agreement with the experimental data at 40 MeV/nucleon, but cross sections are smaller by about a factor of 5, compared to experimen...

Accumulated experimental data on the binding energies for single-particle states in a broad range of nuclei is examined as function constituent number neutrons and protons simple pattern emerges. The dependence neutron protons, or proton neutrons, behave similar to each other across nuclear chart, sign reflects well-known strong attraction. change energy with approximately factor four weaker ma...
