Excitation of resonance transitions of neodymium atom in ultraviolet in e-Nd collisions

The excitation of resonance transitions of neodymium atoms in ultraviolet is investigated using the method of extended crossing beams. The majority of the measured cross sections lie in the range from 10(-17) to 10(-18) cm(2). Thirty-one optical excitation functions are registered upon variation of the electron energy from the excitation threshold to 200 eV. For 39 transitions, a classification within the framework of the known system of terms is suggested.
