High Energy Electron Collision Phenomenon and Electromagnetic Spectrum Simulation Author: Dilip Kumar Kar Abstract High-energy electron collisions play a fundamental role in modern physics, contributing to the understanding of atomic structure, particle interactions, and electromagnetic radiation. This study explores electron behavior under high-energy conditions and presents a simulation framework for analyzing the resulting electromagnetic spectrum. The integration of theoretical models with computational methods enables visualization of radiation patterns and energy transfer mechanisms. Introduction Electron collision phenomena are central to nuclear physics, accelerator science, and materials engineering. When electrons are accelerated to high velocities and collide with atoms or particles, they undergo complex interactions governed by quantum mechanics and electrodynamics. These interactions produce radiation across the electromagnetic spectrum.
