We search for excited and exotic muon states {mu}* using an integrated luminosity of 371 pb{sup -1} of pp collision data at {radical}(s)=1.96 TeV. We search for associated production of {mu}{mu}* followed by the decay {mu}*{yields}{mu}{gamma}. We compare the data to model predictions as a function of the mass of the excited muon M{sub {mu}}{sub *}, the compositeness energy scale {lambda}, and the gauge coupling factor f. No signal above the standard model expectation is observed. We exclude 107<M{sub {mu}}{sub *}<853 GeV/c{sup 2} for {lambda}=M{sub {mu}}{sub *} in the contact interaction model, and 100<M{sub {mu}}{sub *}<410 GeV/c{sup 2} for f/{lambda}=10{sup -2} GeV{sup -1} in the gauge-mediated model, both at the 95% confidence level.
