AbstractAbstract
[en] Cross sections have been measured for the reactions /sup 58,60/Ni(e,e'p) and /sup 58,60/Ni(e,e'α) in the electron-energy range 12--35 MeV. For analysis of the experimental results we used virtual photon spectra calculated in the DWBA. At energies Eγ = 16.0 +- 1.0 MeV for 58Ni and E/sub γ/ = 15.6 +- 1.0 MeV for 60Ni we have observed giant electric-quadrupole resonances which decay mainly by α-particle emission. The integrated cross sections for the reactions 58Ni(γ,α) and 60Ni(γ,α) due to E2 transitions are respectively 5.4 +- 1.4 and 6.0 +- 3.0 mbxMeV, which amounts to 47 +- 12% of the total strength of isoscalar E2 transitions for 58Ni and 56 +- 28% for 60Ni. The integrated cross sections for these same reactions due to E1 transitions are 15.9 +- 2.3 and 16.9 +- 4.8 mbxMeV, which amount to 1.7 +- 0.3% of the value given by the sum rule for electric-dipole transitions for 58Ni and 1.8 +- 0.5% for 60Ni. The measured integrated cross sections for the reactions /sup 58,60/Ni(γ,p) are 539 +- 33 and 300 +- 20 mbx MeV
