Charge Spectrometry forKr79-Br79

The distribution in charge of the ${\mathrm{Br}}^{79}$ atoms formed in the complex electron capture and ${\beta }^{+}$ decay of radioactive ${\mathrm{Kr}}^{79}$ has been found to consist of two components; one to be mostly associated with the ${\beta }^{+}$ transitions, and the other with the electron capture transitions. Because of a difference in instrumental efficiency, the relative intensity of the two components is undetermined in the present work, but if the value of 9.3 is assumed for the total $\mathrm{e}\mathrm{l}\mathrm{e}\mathrm{c}\mathrm{t}\mathrm{r}\mathrm{o}\mathrm{n}-\mathrm{c}\mathrm{a}\mathrm{p}\mathrm{t}\mathrm{u}\mathrm{r}\mathrm{e}/{\beta }^{+}$ ratio, then the spectrum for the successive charges -1, 0, +1...+13 is as follows (figures in percent): 7.7, 3.7 (estimated), 4.0, 4.7, 12.7, 16.0, 14.3, 13.6, 11.3, 7.7, 3.3, 0.68, 0.13, 0.054, and 0.014, respectively.
