Abstract

We measured simultaneously pp elastic and quasielastic (p,2p) scattering in hydrogen, deuterium, and carbon for momentum transfers of 4.8 to 6.2(GeV/c)2 at incoming momenta of 5.9 and 7.5GeV/c and center-of-mass scattering angles in the range θc.m. = 83.7°-90°. The nuclear transparency is defined as the ratio of the quasielastic cross section to the free pp cross section. At incoming momentum of 5.9GeV/c, the transparency of carbon decreases by a factor of 2 from θc.m. ≃ 85° to θc.m. ≃ 89°. At the largest angle the transparency of carbon increases from 5.9 to 7.5GeV/c by more than 50%. The transparency in deuterium does not depend on incoming momentum nor on θc.m..
