摘要
The cross section for the Mg25(p,2p)Na24 reaction was measured at 8 energies from 0.43 GeV to 2.7 GeV. The cross sections increased from 26.7±0.8 mb at 0.43 GeV to 31.9±1.0 mb at 1.01 GeV. As expected from the clean-knockout mechanism, this increase is related to a large increase in free-particle cross section. An empirical expression which takes into account the momentum of the struck particle and a rough estimate of attenuation factors gives a reasonable fit to all cross-section data from 0.15 to 2.7 GeV. Mont Carlo calculations at 0.15 GeV also agree with the experimental cross sections. Effective forward and backward ranges for Na24 in Mg25 were measured, using the thick-target-thick-catcher technique. © 1969 The American Physical Society.
