Muonium centers are readily formed in a wide variety of insulators and semiconductors due to enormous capture cross sections of the unscreened Coulomb potential produced by positive muons. Following the initial capture, different processes of electro

We used the low-energy μ SR technique (LE- μ SR ) to extend our previous studies on the energy dependence of muonium (Mu) states in Si and insulators [T. Prokscha, E. Morenzoni, D.G. Eshchenko, N. Garifianov, H. Gluckler, R. Khasanov, H. Luetkens,

We have performed measurements on crystals of KH 2 PO 4 (KDP, ferroelectric (FE) transition at T FE = 123 K ), NH 4 H 2 PO 4 (ADP, antiferroelectric (AFE) transition at T AFE = 148 K ) and deuterated ADP (DADP, ND 4 D 2 PO 4 , antiferroelectric trans

The PSI low-energy $��$SR spectrometer is an instrument dedicated to muon spin rotation and relaxation measurements. Knowledge of the muon beam parameters such as spatial, kinetic energy and arrival-time distributions at the sample position are i

We present a direct spectroscopic observation of a shallow hydrogen-like muonium state in SrTiO$_3$ which confirms the theoretical prediction that interstitial hydrogen may act as a shallow donor in this material. The formation of this muonium state

Charge differentiation in μ+ or muonium (Mu) as a consequence of the slowing down of μ+ in matter is of fundamental interest in the μSR method. It is also of relevance for understanding the moderation process of μ+ in van der Waals solids like s-

We report an observation of the formation of muonium [Mu=(mu(+)e(-)) bound state] with kinetic energies between 1 and 40 keV on 500-nm-thick solid argon, xenon, and nitrogen (N-2) layers. The thin films are deposited on a 250-mu m-thick aluminum targ

We report on Muonium (Mu) emission into vacuum following {\mu}+ implantation in mesoporous thin SiO2 films. We obtain a yield of Mu into vacuum of (38\pm4)% at 250 K temperature and (20\pm4)% at 100 K for 5 keV {\mu}+ implantation energy. From the im

We report the first measurements of the positive-muon spin depolarization in liquid3He. The relaxation of the muon and muonium precession has been studied in transverse, longitudinal, and zero magnetic fields in the temperature range 0.5–2.5 K. The
