    A search for decays of the Higgs boson into a pair of new spin-zero particles, H→aa, where the a-bosons decay into a b-quark pair and a muon pair, is presented. The search utilizes 36.1 fb-1 of proton–proton collision data at $\sqrt{s}$ = 13 TeV recorded by the ATLAS experiment at the LHC in 2015 and 2016. No significant deviation from the Standard Model prediction is observed. Upper limits at 95% confidence level are placed on the branching ratio (δH/δSM) x $\mathcal{B(H→aa→bbμμ)}$, ranging from 1.2 10-4 to 8.4 x 10-4 in the a-boson mass range of 20–60 GeV. Model-independent limits are set on the visible production cross-section times the branching ratio to the bbμμ final state for new physics, δVIS(X) x $\mathcal{B(X→bbμμ)}$, ranging from 0.1 fb to 0.73 fb for mμμ between 18 and 62 GeV.
