When a quantum particle with positive energy encounters a Dirac delta potential well, it doesn’t get trapped — instead, it partially reflects and partially transmits through the point-like potential. This simple yet profound model captures the essence of quantum scattering, showing how even the thinnest barrier can alter a particle’s path, phase, and probability of transmission.
