Our experimental EICP data analysis for zinc and cadmium atoms allowed us to find some helical structures in gamma function in energy and scattering angle domains. They correspond to the special conditions in which only one of two scattering channels is available. Therefore the electron charge cloud is rotationally symmetric (PL=0), the alignment angle parameter is undefined, and the angular momentum transfer reaches the maximum value (+/-1). Due to their local and narrow character, such structures can be an exact tool for verifying theoretical models with experimental results.
