Exploiting a five-year span of data, we present improved timing solutions forthe five millisecond pulsars known in the globular cluster NGC 6752. Theyinclude proper motion determinations for the two outermost pulsars in thecluster, PSR J1910-5959A and PSR J1910-5959C. The values of the proper motionsare in agreement with each other within current uncertainties, but do not match(at 4 sigma and 2 sigma level respectively) with the value of the proper motionof the entire globular cluster derived in the optical band. Implications ofthese results for the cluster membership of the two pulsars are investigated.Prospects for the detection of the Shapiro delay in the binary systemJ1910-5959A are also discussed.Comment: 8 pages, 3 figures, accepted for publication in Ap
