Electrodisintegration ofNi58,Ni60, andNi62

The ($e, p$) and ($e, \alpha$) cross sections for targets of ${}_{}{}^{58}{}_{}{}^{}\mathrm{Ni}$, ${}_{}{}^{60}{}_{}{}^{}\mathrm{Ni}$, and ${}_{}{}^{62}{}_{}{}^{}\mathrm{Ni}$ have been measured in the electron energy range 16-100 MeV. They have been analyzed using the distorted-wave Born approximation $E1\mathrm{}$ and $E2\mathrm{}$ virtual photon spectra. Protons are emitted primarily following $E1\mathrm{}$ absorption but $\alpha$-emission results from a combination of $E1\mathrm{}$ and $E2\mathrm{}$ absorption.
