Aj. Simon et al., ABSOLUTE PP-ELASTIC CROSS-SECTIONS FROM 492 TO 793 MEV USING CH2 TARGETS, Physical review. C. Nuclear physics, 53(1), 1996, pp. 30-34
pp-elastic differential cross sections are reported at 492 MeV from 40
degrees to 90 degrees, and at 576, 642, 728, and 793 MeV from 75 degr
ees to 90 degrees c.m., with an absolute accuracy of less than 1%. The
se data, obtained with polyethylene targets, agree with recent measure
ments at the same energies obtained with a liquid-hydrogen target.
