Phys. Rev. Lett. 81, 5085–5088 (1998)Nuclear Transparency in Large Momentum Transfer Quasielastic ScatteringReceived 22 May 1998; published in the issue dated 7 December 1998 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.. © 1998 The American Physical Society URL:
