In 1961, physicist Ugo Fano provided the first theoretical explanation to an anomalous asymmetry observed in the spectral profiles of noble gases. He put forth an impactful interpretation of this phenomenon, now called 'Fano resonance,' stating that if a discrete excited state of a system falls within the energy range of a continuum of other possible states, these two can interfere with each other and give rise to abnormal peaks and dips in the system's frequency response.
