Figure 2.

Plots of Rb-82 positron energy spectrum contributions N₁ and N₂, which have end point energies of $E_1^{\text{max}}=3.379\text{MeV and}{E}_2^{\text{max}}=2.603\text{MeV}$ with branching ratios of 0.833 and 0.117, respectively, as well as the overall combined energy spectrum. All curves in the figure have already been normalized to unit area. The overall spectrum is considerably more similar to N₁ because of the associated large branching ratio of 0.833.
