Intensity ratios ofL, M, N, O subshell conversion electrons inM3 andE4 transitions

Abstract

Abstract. Conversion electron spectra from three E3 and four M4 transitions in l~ 1~ 115In, lZSTe, 134Cs, 135Ba, 193Ir have been measured with the (z/2)lflJ iron-free spectrometer with momentum resolution 0.5 x 10 -3 to 1 X 10 -3. Intensity ratios of L, M, N, O conversion electrons show no significant departures from theory, but there is some evidence of error in the absolute values of outer-shell conversion coefficients calculated by the approximate method of Dragoun et al.

Discrepancies among theoretical and experimental internal conversion coefficients

“…This discrepancy is usually quoted relative to the most sophisticated theoretical values-those of Hager and Seltzer [3]-but it persists with other theoretical treatments. There does not appear to be an analogous effect for M1 transitions [4] or for E3 and M4 transitions [5]. Hager and Seltzer [6] have calculated a correction to the E2 cases to include 2-electron processes, and find that this is sufficient to remove the anomaly.…”
