Radiative deexcitation (RD) of the metastable 2S state of muonic hydrogen and deuterium atoms has been observed. In muonic hydrogen, we improve the precision on lifetime and population (formation probability) values for the short-lived μp(2S) component, and give an upper limit for RD of long-lived μp(2S) atoms. In muonic deuterium at 1 hPa, 3.1±0.3% of all stopped muons form μd(2S) atoms. The short-lived 2S component has a population of 1.35 −0.33+0.57% and a lifetime of τ2Sshort(μd)=138 −34⁺³² ns. We see evidence for RD of long-lived μd(2S) with a lifetime of τ2Slong(μd)=1.15 −0.53+0.75μs. This is interpreted as formation and decay of excited muonic molecules.
