  The J/{\psi} and {\Upsilon}(1S) production cross-sections are measured in
proton-proton collisions using the ATLAS detector at the LHC. Differential
cross-sections are measured as a function of transverse momentum and rapidity.
Results are compared to QCD predictions. A new {\chi}b state has been observed
though radiative transitions to the {\Upsilon}(1S) and {\Upsilon}(2S) states.
