Description
Summary:The expressions for matrix elements of electric multipole operator coupling levels with various types of vector coupling are given. The cases of different types of coupling in the initial and final levels are also considered. Selection rules for the mentioned cases are established. They are expressed by polygonal rules presenting nonvanishing conditions of j-coefficients appearing in expressions of matrix elements of electric multipole operator. Maximum number of sides in these polygons is equal to five. (Author) Edited machine trans. of Lietuvos Fizikos Rinkinys (Lithuanian SSR) 1961, v. 1, no. 1/2, p. 21-32.
