Molecular effects in low-energy muon transfer from muonic hydrogen to oxygen

I. Boradjiev, A. Adamczak, D. Bakalov +24

In the present study we determine from the available experimental data the cross section of muon transfer to molecular oxygen at low energies with account of the oxygen molecule st…

Measurement of the muon transfer rate from muonic hydrogen to oxygen in the range 70-336 K

C. Pizzolotto, A. Sbrizzi, A. Adamczak +39

The first measurement of the temperature dependence of the muon transfer rate from muonic hydrogen to oxygen was performed by the FAMU collaboration in 2016. The results provide ev…
