Quantum Scattering Phase Shifts for Yukawa, Double Yukawa and Exponential Screened Coulomb Potentials

These datasets contain quantum scattering phase shifts for the s-wave ($\delta_0$), p-wave ($\delta_1$), and d-wave ($\delta_2$), accurately computed using the Variable Phase Method (VPM), for Yukawa, Double Yukawa, and Exponential Cosine Screened Coulomb potentials. Each file consists of five columns corresponding to k, q, delta_0, delta_1, and delta_2. Here, k and q represent the magnitude of the incident plane wave and the screening parameter, respectively, in appropriate scattering units: $\hbar=2m =1$, see F. Calogero, Variable Phase Approach to Potential Scattering, Elsevier, 1967. More specific details about the computations, can be found in: Alessandro Romualdi, Gionni Marchetti, Machine learning S-wave scattering phase shifts bypassing the radial Schrödinger equation, European Physical Journal B, 94, 249 (2021).
