Some peculiar structures in scattering angle–collision energy dependence of the alignment angle parameter have been found in data sets for zinc and cadmium atoms. They are accompanied by zeros of the shape parameter value, where the maximum angular momentum transfer occurs. The reported structures are also predicted in data for other atoms with two valence electrons. There is a need for theoretical predictions on impact energy and scattering angles corresponding to such conditions
