Why does binding energy decrease?
Why does binding energy decrease? The above figure illustrates that as the atomic mass number increases, the binding energy per nucleon decreases for A > 60. As the repulsive forces are increasing, less energy must be supplied, on the average, to remove a nucleon from the nucleus. In other words, the BE/A has decreased. What […]

How do neutrons kill?
How do neutrons kill? Since neutrons are scattered and absorbed by air, neutron radiation effects drop off rapidly with distance in air. The intense pulse of high-energy neutrons generated by a neutron bomb is the principal killing mechanism, not the fallout, heat or blast. Does a neutron bomb exist? A neutron bomb is actually a […]
