    "abstract": "We present a new procedure which enables to extract a scattering matrix\n$S(l)$ as a complex function of angular momentum directly from the scattering\ndata, without any a priori model assumptions implied. The key ingredient of the\nprocedure is the evolutionary algorithm with diffused mutation which evolves\nthe population of the scattering matrices, via their smooth deformations, from\nthe primary arbitrary analytical $S(l)$ shapes to the final ones giving high\nquality fits to the data. Due to the automatic monitoring of the scattering\nmatrix derivatives, the final $S(l)$ shapes are monotonic and do not have any\ndistortions. For the $^{16}$O-$^{16}$O elastic scattering data at 350 MeV, we\nshow the independence of the final results of the primary $S(l)$ shapes.\nContrary to the other approaches, our procedure provides an excellent fit by\nthe $S(l)$ shapes which support the ``rainbow\u0027\u0027 interpretation of the data\nunder analysis.",
