Nucleon knock-out reactions, not so simple but still of great interest

Jose Benlliure Anaya (Universidade De Santiago de Compostela, Spain)

Nucleon knock-out reactions at energies well above the Fermi energy have long been proposed as a spectroscopic tool because of the relatively simple description of this reaction mechanism using the Glauber model. However, the puzzle of the quenching of the spectroscopic factors in single-nucleon knockout processes and the overestimated production of neutron-rich nuclei in multi-proton knockouts have revealed some shortcomings in the assumptions behind the Glauber model.
In this seminar I will present a systematic study of nucleon knock-out on different tin isotopes, showing the above mentioned limitations of the reaction model, but also a case of success where this reaction channel is used for detailed studies of the fission process.
