Essentially it is the angular distribution of the neutron after scattering.

A differential cross section is a measurement used in particle and nuclear physics to describe the probability of a particular interaction between particles. It is a function of the angle and energy of the particles involved.

Differential cross section is calculated by taking the ratio of the number of particles scattered in a particular direction to the intensity of the incident beam of particles and the density of the target material. This calculation also takes into account any other factors that may affect the scattering, such as the size and shape of the target.

The unit of measurement for differential cross section is typically given in units of area, such as barns (b) or femtobarns (fb). These units are used to represent the probability of a scattering event occurring, with larger values indicating a higher probability.

Differential cross section allows scientists to understand the underlying physical processes that occur when particles interact. By studying the behavior of particles in different scattering angles and energies, researchers can gain insights into the fundamental forces and particles that make up our universe.

Differential cross section is often used in the analysis of experimental data to compare the results with theoretical predictions. By measuring the differential cross section at different angles and energies, scientists can test the validity of existing theories and potentially discover new phenomena.
