Abstract
This paper is the second part of two back-to-back papers concerning electro n-impact excitation of Kr. This part concerns excitation of the individual levels that constitute the 4p(5)5p, 4p(5)4d and 4p(5)6s configurations of K r, at incident electron energies (E-0) of 20.0 and 15.0 eV, for scattering angles (theta) ranging from 10 degrees to 130 degrees. As in part I, excita tion cross sections are measured and calculated using the R-matrix (RM) and the unitarized first-order many-body theory (UFOMBT) methods. Comparisons between the present experimental and theoretical results, and also with oth er experimental results, are presented.
