The diamagnetic states formed by muon implantation in alkali halides are to be characterised, and their diffusion studied, by means of RF final-state analysis. The 90° pulse...

This proposal is part of a long-range program aiming at determining the stable charge-stateconfigurations, site and impurity energy levels (donor and/or acceptor) of hydrogen in...

Since ancient times it has been known that using boiling water to prepare tea ¿burns¿ the brew destroying the teas flavours & beneficial nutrients. One aspect of a ¿burnt¿...

Molecular modelling suggests that the antioxidant molecule EGCG "folds up" around the radical it captures, and therefore should shield the spin density from the environment....

We propose to characterize the basic muonium/hydrogen configurations in selected rare-earth sesquioxides with the basic crystallographic structures: neodymium oxide (hexagonal A...

Recent muon level-crossing measurements in the stable orthorhombic alpha-phase of sulphur indicate the existence of a radical state, with an interesting temperature evolution....

Rutile titanium dioxide is one of the most relevant oxide materials, where the impurity physics of hydrogen has recently been devoted much attention. Existing ab-initio...

This proposal is part of a long-range program aiming at determining the stable charge-state configurations, site and impurity energy levels (donor and/or acceptor) of hydrogen...

We have observed an anomalous monotonically increasing longitudinal field relaxation rate in LiY_(1-x)Ho_xF_4 for applied fields above 1000 G (along the c-axis) and at a...

The elusive OMu radical is believed to be formed by muonium reaction with nitrous oxide but has never been directly observed. It would be invisible to transverse-field muon spin...

Our recent experiment showed that muons implanted into black phosphorus (the most stable allotrope of the element, with a low band gap of 0.3eV) are apparently diamagnetic, with...

Muon interactions with quadrupolar nuclear spins have occasionally been studied by theirlevel crossing resonance spectra. In an ideal case the quadrupole resonance level...

Following recent experiments in which the shallow donor muon states in semiconductors are found to have significant electron polarisation at low temperatures and high fields, we...

This proposal is part of a long-range program aiming at determining the stable charge-state configurations, site and impurity energy levels (donor and/or acceptor) of hydrogen...

Ca3CoMnO6 has alternating ions in ferromagnetic Ising chains that are antiferromagnetically coupled on a triangular lattice and realizes an important model in frustrated...

The usual assumption that the muon's polarisation relaxes to zero at long times may be incorrect at high B and low T: for 5T and 30mK the Brillouin function gives P=49%. We plan...

This experiment aims at studying the magnetic behaviour of the molecular square complex {[Fe{B(pz)_4}(CN)_3]_2[Co(bik)_2]_2}(ClO_4)_2 . 3H_2O [B(pz)_4 = tetrapyrazolylborate,...

Experiment is proposed to identify magnetic polaron bound to the muon using RF-muSR. In recent experiment at TRIUMF magnetic polaron was found in transverse field and its...

At low temperatures and high magnetic fields, the electron in a muonium or radical state may be polarised if it has an opportunity to reach thermal equilibrium. Such a...

Previous muon experiments have identified a muonium state in the commonly occuring, but complex, beta rhombohedral form of elemental boron. To complement recent theoretical work...
