Abstract
A Si detector telescope, in which alternating thick and thin Si elements served as both targets and detectors, was used to measure the energy dependence of the inclusive one-proton-removal cross sections of , , and on a Si target. A similar detector telescope was used to measure both and for ; of is more than twice as large as of and almost as large as of . The measurements were compared with shell model calculations using eikonal reaction theory. The quenching factors (the ratio of the measurement to the theoretical prediction) for and were near unity, as at higher energies. They also agreed with those measured recently for those nuclei on a C target at . For the quenching is greater with . This is comparable to the value deduced at energies above .
