The distribution in charge of the product atoms of the radioactive decay Xe/sup 133-Cs/sup 133/ was examined under magnetic analysis. The relative intensities are found to be as follows, expressed in percent of the decay events. and going, respectively, from charge 1 through charge charge spectrum. the initial part (charges l through 4) is attributed mainly to atoms that escape internal conversion. and the subsequent rise to a maximum at charge 8 and decrease to charge 23 is attributed to atoms that suffer internal converson. The ratio of the intensities of the two parts of the distribution gives a total internal conversion coefficient for the K, L. and M shells of l.4. in rough agreement with work of others. Comparison is made with the charge spectrum arising from internal conversion in Xe/sup 131m/-Xe/sup 131, which had previously been measured in the same apparatus. From the low-charge end of the spcctrum. the probabilites of electron loss as a result of the beta decay alone are derived as follows: no-electron loss 0.8: l-electron loss. 0.08: 2-electron loss. 004: 3-eleetron loss. 0.03. The high-charge side of the spectrum shows a shallowdip in the region of charges l2, l3, and l4 and beyond that point there is relatively more intensity in Xe/sup 133/ Cs/sup 133/ than there is in Xe/sup 133m/-Xe/sup 131/. The difference in shape probably results both from tae hsgher K/(L + M) conversion ratio of Xe/sup 133/-C/sup 133/ as compared with Xe/sup 131m/-Xe/sup 131/, and from the fact that the beta emission in Xe/sup 133/-Cs 133/ introduces electron loss by shake-off. The dip at charges l2, l3, and 14 suggests an underlying structure in the total distribution, comprising subspectra associated with the individual electron shells in which the vacancy cascades originate.
