The authors have measured the differential cross section for the inclusive production of {psi}(2S) mesons decaying to {mu}{sup +}{mu}{sup -} that were produced in prompt or B-decay processes from p{bar p} collisions at 1.96 TeV. These measurements have been made using a data set from an integrated luminosity of 1.1 fb{sup -1} collected by the CDF II detector at Fermilab. For events with transverse momentum p{sub T}({psi}(2S)) > 2 GeV/c and rapidity |y({psi}(2S))| < 0.6 we measure the integrated inclusive cross section {sigma}(p{bar p} {yields} {psi}(2S)X) {center_dot} Br({psi}(2S) {yields} {mu}{sup +}{mu}{sup -}) to be 3.29 {+-} 0.04(stat.) {+-} 0.32(syst.) nb.
