   .. py:method:: angle(free_length, x_direction: numpy.array, y_direction: numpy.array, slab: npac_detector.material.MaterialSlab) -> float

      Computes the scattering angle of the particle as a function of the material slab hitted

      :param free_length: Distance travelled by the particle before entering the slab, in mm
      :param x_direction: x composant of the particle's unitary momentum vector
      :param y_direction: y composant of the particle's unitary momentum vector
      :param slab: Material with a definite thickness and material.
      :return: scattering angle in rad
