Cross sections have been measured for Ni (e,e'p) and Ni \e,e'a) reactions. Virtual photon spectra calculated in the distorted wave Born approximation have been used to analyze the experimental results. An electric quadrupole (E 2) giant resonance has been found which decays principally by the emission of ^-particles.
