| Résumé : | I first recall the principle of phase-shift analysis and effective-rangeexpansions for charged-particle elastic scattering. Then, I show howPadé expansions of effective-range functions can be used to linkproperties of subthreshold bound states, in particular asymptoticnormalization constants, to low-energy elastic-scattering phase shifts.Finally, the method is applied to the C12+alpha system, of which theimportance in nuclear astrophysics is recalled. |
