pienkulmasäteilyn

Pienkulmasäteily refers to radiation that travels within a very narrow angular range relative to a reference direction. This concept is particularly relevant in fields like optics and particle physics. In optics, it describes light beams that are highly collimated, meaning their rays are nearly parallel and converge or diverge very slowly. This is characteristic of lasers, where the emitted light is highly directional. A narrow angular spread implies a low divergence angle.

In particle physics, pienkulmasäteily can describe the scattering of particles at very small angles. This is often observed in high-energy collisions where particles interact and deviate only slightly from their original trajectories. Studying these small-angle interactions can provide valuable information about the fundamental forces and properties of the particles involved. The detection and analysis of pienkulmasäteily often require specialized equipment designed to measure precise angular deviations. This phenomenon is also sometimes referred to as small-angle scattering or small-angle deflection.
