WebThe center of the target is located in the geometrical center of the iron shell. For monitoring the neutron source strength, the alfa particles generated in the deuterium-tritium reaction were detected at 175 deg. through a 1 mm diameter collimator by a silicon surface barrier (SSB) detector. The ion pulse width is 2.5 ns. WebMany models describe the way protons and neutrons are arranged inside a nucleus. One of the most successful and simple to understand is the shell model. In this model the protons and neutrons occupy separate systems of shells, analogous to the shells in which electrons are found outside the nucleus.
