“…These conversion coefficients, as well as the Lj/Lu/ Liu ratios, correspond with the assignment to E2 radiation (from calculated conversion coefficients of Gellman, Griffith, and Stanley 16 ), as already pointed out by Rosenblum, Valadares, and Guillot. 13 Attempts have been made [17][18][19] to assign the radiation uniquely by alpha-gamma angular correlations, but, although there is strong evidence 18 * 19 for an electric quadrupole component, the correlation is not exact.J Nevertheless, the preponderance of evidence in this case, as well as for even-even nuclei in general, points to 2+ for the first excited state.…”
