Physicists Rafael de la Madrid and Rodolfo Id Betan have extended Gamow’s Golden Rule to multichannel quantum scattering, providing a unified framework for analyzing resonances with multiple decay pathways. The study derives key quantities—decay distributions, partial decay constants, widths, and branching fractions—enabling precise predictions of resonance behavior in complex systems like nuclear or molecular physics. A coupled-channel square well potential model demonstrates the theory’s practical application, validating its accuracy in simulating real-world quantum decay processes. Published in March 2026, the work bridges quantum physics and nuclear theory, offering tools to refine experimental designs in fields from particle physics to quantum chemistry. This advancement could improve resonance spectroscopy techniques, enhancing control over unstable quantum states in both fundamental research and applied technologies.
