This paper presents the first measurement of the differential B{sup {plus_minus}}and B{sup o} cross-sections, d{sigma}/d{sub PT} in p{bar p} collisions at {radical}s = 1.8 TeV. The data sample used represents an integrated luminosity of 19.3 {plus_minus} 0.8 pb{sup {minus}1} accumulated by the Collider Detector at Fermilab (CDF). The cross-sections are measured over the PT range 6--15 GeV/c in the central pseudorapidity region {vert_bar}{eta}{vert_bar} < 1 by fully reconstructing the B meson decays B{plus_minus} {yields} and J/{psi}K{sup *o}, where the J/{psi} is required to decay to two muons, and the K{sup *o} is required to decay to K{plus_minus}{pi}{plus_minus}. The results are compared to the theoretical QCD prediction calculated at next-to-leading order.
