Looks like an error to me...Clara Chung said:
Yes, it should be zero :)jtbell said:Yes, insert ##n_t l## into (9.9) in such a way that the units are consistent on both sides.
A physical reality check: if ##l = 0## or ##n_t = 0##, i.e. the target disappears completely, what should we expect ##J_s## to be, regardless of ##J_i##?
A differential cross section is a measure of the probability of a particle interacting with another particle in a given direction and energy. It is commonly used in particle physics to study the scattering of particles.
The differential cross section is calculated by taking the ratio of the number of particles scattered in a particular direction to the incident flux of particles. It is then normalized by the solid angle and the target density.
The differential cross section provides valuable information about the internal structure of particles and the nature of their interactions. It can also be used to test theoretical models and make predictions about future experiments.
Yes, the differential cross section can be measured experimentally by detecting the scattered particles in different directions and energies. This data is then used to calculate the differential cross section and compare it to theoretical predictions.
The differential cross section generally increases with increasing energy of the particles. This is because higher energy particles have a greater chance of interacting with other particles. However, the exact dependence on energy can vary depending on the type of interaction and the properties of the particles involved.
