English We present experimental results of µ-atomic and µ-molecular processes induced by negative muons in pure helium and helium-deuterium mixtures. The experiment was performed at the Paul Scherrer Institute (Switzerland). We measured relative intensities of muonic x-ray K series transitions in (µ3,4He)* atoms in pure helium as well as in helium-deuterium mixtures. The dµ³He radiative decay probabilities for two different helium densities in D2+³He mixture were also determined. Finally, the qHe1s probability for a dµ atom formed in an excited state to reach the ground state was measured and compared with theoretical calculations using a simple cascade model.
