Photon diffractive dissociation, gamma p --> Xp, has been studied at HERA with the ZEUS detector using ep interactions where the virtuality Q(2) Of the exchanged photon is smaller than 0.02 GeV(2). The squared four-momentum t exchanged at the proton vertex was determined in the range 0.073 < \t\ < 0.40 GeV(2) by measuring the scattered proton in the ZEUS Leading Proton Spectrometer. In the photon-proton centre-of-mass energy interval 176 < W < 225 GeV and for masses of the dissociated photon system 4 < M(x) < 32 GeV, the t distribution has an exponential shape, dN/d\t\ proportional to exp (-b\t\), with a slope parameter b = 6.8 +/- 0.9 (stat.)(-1.1)(+1.2) (syst.) GeV(-2). RI De Pasquale, Salvatore/B-9165-2008; Wing, Matthew/C-2169-2008; Bashkirov, Vladimir/A-4818-2008; Doyle, Anthony/C-5889-2009; Gladilin, Leonid/B-5226-2011; Golubkov, Yury/E-1643-2012
