3. Types of data measurement
The modeling of neutron cross sections is based on nuclear reaction models whose parameters are not currently predicted with sufficient accuracy by microscopic physical theories. They are therefore adjusted to a set of observations (measurements). Three types of experiments are then analyzed: microscopic experiments, analytical integral experiments targeting the influence of a particular nuclide, and integral experiments (known as "mock-ups"), representative of reactor concepts.
3.1 Microscopic experiments
Microscopic (or differential) experiments are mainly those which measure certain attributes of the particles (projectile and ejecta) involved in the reaction: their type (neutron, gamma, alpha, electron, etc.), their energy, their spin, and so on. Of particular...
