Abstract
The contribution of two-step processes in the reaction 12C(e, e′ p) 11B has been studied under quasi-elastic conditions. Cross sections were measured for the transitions to the 5 2 − state at an excitation energy of 4.445 MeV and the ( 7 2 −, 1 2 +) -doublet at 6.767 MeV in the missing momentum range between 140 MeV/ c and 220 MeV c. The excitation of the 5 2 − states, which was never observed before in (e, e′ p) experiments on 12C, can be quantitatively described as being due to a two-step process. A good description of the excitation of the ( 7 2 − , 1 2 +) doublet is obtained with a coupled-channels calculation includi both direct knock-out and two-step contributions.
