Neutron cross section according to its neutron cross section and how it reacts to an incident neutron. Nuclides that tend to absorb a neutron and either decay or keep the neutron in its nucleus are neutron absorbers and will have a "capture cross section" for that reaction. Isotopes that fission, are fissionable fuels and have a corresponding "fission cross section". The remaining isotopes will simply scatter the neutron, and have a "scatter cross section". Some isotopes, like uranium-238, have nonzero cross sections of all three. Isotopes which have a large scatter cross section and a low mass are good neutron moderators (see chart
Horizontal escalation it meant they were now capable of making conventional defense mechanisms in the West. Horizontal escalation could also be used to essentially fix the Soviet forces at a specific location to prevent them from placing reinforcements at the desired location of attack. However, horizontal escalation will only turn out well, if there is a respectable enough bargaining chip like that of the Persian Gulf oil; essentially how valuable is the territory/object to your opponent? However, it was not the United States Navy that dictated where the Soviet Union positioned its forces. It was primarily Chinas forces that dictated where the
