摘要：
The (e,p) and (e,α) cross sections for targets of Ni58, Ni60, and Ni62 have been measured in the electron energy range 16-50 MeV. They have been analyzed using the distorted-wave Born-approximation E1 and E2 virtual-photon spectra. Protons are emitted primarily following E1 absorption but α emission results from a combination of E1 and E2 absorption. The E2 isoscalar giant resonance decays predominantly by α emission for these nuclei. © 1979 The American Physical Society.
