Fig. 2: Fit of the angle-resolved resonance profiles to a model based on Fano interference.

a Theoretically determined angle and energy-dependent cross section from coupled channel scattering calculations (dotted blue curves) are fitted to Fano interference model (solid blue lines) in the vicinity of the resonance at 4.8 K. b The experimentally measured cross sections (marked in red with error bars, where the error bars indicate standard deviation) are shown along with their corresponding fit to the model (solid red lines). For comparison, we also show grey curves in column a generated by approximating the value of background phase and amplitude from quantum scattering calculations and inserting it in Eq. 2. The quality of the fits is assessed by the R-squared (\({R}^{2}\)) values. The different angular ranges (i)–(iv) are same as labelled in Fig. 1.
