Abstract: | We measured the total cross section for p scattering at at the CERN ISR, using the direct, total-rate method. The result obtained, , shows that, in common with σtot(pp), this cross section also starts to rise in the ISR energy range. We remeasured the total cross section for pp scattering at the same energy, obtaining σtot(pp) = 43.26 ± 0.33 mb, and found for the difference, , a value of 1.44±0.45 mb. |
