摘要: Abstract Photoproton energy and angular distributions have been measured for the (e, e'p) reaction on 90 Zr, 89 Y 88 Sr at a number of electron bombarding energies. Proton groups passing through resonances are found in distributions. The dependence residual states is studied, it that large contribution from core excitation exists strong E1 IAS. configurations these IAS discussed with respect to Cross sections (γ, p 0 ) were extracted photoproton spectra. results show coherent T +1 resonance good agreement theory. compared various types nuclear reactions. Strengths IAR depend type reaction.
