  Results on diffractive photoproduction of psi(2S) mesons are presented using
data collected between 1996 and 2000 with the H1 detector at the HERA ep
collider. The data correspond to an integrated luminosity of 77 pb^(-1). The
energy dependence of the diffractive psi(2S) cross section is found to be
similar to or possibly somewhat steeper than that for J/psi mesons. The
dependences of the elastic and proton dissociative psi(2S) photoproduction
cross sections on the squared momentum transfer t at the proton vertex are
measured. The t-dependence of the elastic channel, parametrised as e^(bt),
yields b_(el)^(psi(2S))=(4.31+-0.57+-0.46) GeV^(-2), compatible with that of
the J/psi. For the proton dissociative channel the result
b_(pd)^(psi(2S))=(0.59+-0.13+-0.12) GeV^(-2) is 2.3 standard deviations smaller
than that measured for the J/psi. With proper account of the individual
wavefunctions theoretical predictions based on perturbative QCD are found to
describe the measurements well.
