CDF collaboration has measured the differential elastic cross section d{sigma}{sub el}/dt, the single diffraction dissociation double differential cross section d{sup 2}{sigma}{sub sd}/dM{sup 2}dt and the total inelastic cross section in antiproton-proton collisions at center of mass energies {radical}s=546 and 1800 GeV. The elastic scattering slope is 15.28{plus_minus}0.58 (16.98{plus_minus}0.25) GeV{sup {minus}2} at {radical}s = 546 (1800) GeV. Using the luminosity independent method, (1 + {rho}{sup 2}){sigma}{sub T} is measured to be 62.64{plus_minus}0.95 (81.83{plus_minus}2.29) mb at {radical}s = 546 (1800) GeV. Assuming {rho} = 0.15, the elastic, total and signal diffraction cross sections are {sigma}{sub el} = 12.87{plus_minus}0.30, {sigma}{sub T} = 61.26{plus_minus}0.93 and {sigma}{sub sd} = 7.89{plus_minus}0.33 mb ({sigma}{sub el} = 19.70{plus_minus}0.85, {sigma}{sub T} = 80.03{plus_minus}2.24 and {sigma}{sub sd} = 9.46{plus_minus}0.44 mb) at 546 (1800) GeV.
