Radio-frequency muon spin resonance is a powerful technique for studying free radicals and their reaction kinetics, but it has not yet been used to study complex reactions in...

To the best of our knowledge, there is no previous work on using muons to measure photo-excited states in organic semiconductors or related materials. Our photo-excitation ideas...

We propose an investigation of the magnitude and fluctuations of internal magnetic fields in Mn-doped ZnGeP2. This chalcopyrite structured semiconductor has a ferromagnetic (FM)...

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...

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...

Radio-frequency muon spin resonance is an exceptional technique for studying free radicals, but it has not been applied to study radicals in the gas phase. In a previous...

In a previous experiment (RB910492) we have made preliminary measurements of the rates of addition of muonium to vitamins C and E, as suggested by the ISIS panel. These rates...

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

The Mn6 single molecule magnet shows to date the highest anisotropy barrier for a transition metal cluster. Low lying excited states in the energy level diagram of the molecule...

The [FeFe]-hydrogenase enzymes are some of the best catalysts know for generating hydrogen. We have an ongoing programme to understand how their chemistry works, and to...

Metallic systems with one-dimensional chain-like atomic structure can support unusual mechanisms for electron pairing leading to superconductivity. K_2Cr_3As_3 is one of a...

This experiment proposes the continuation of a study, initiated at J-PARC, on a new type of activated carbon material, with a pore structure and chemistry "tunable" in a manner...

We propose a set of measurements using the HiFi spectrometer in which muon level-crossing resonances are used to probe the internal field inside antiferromagnets in which the...

Frustrated compounds belonging to the pyrochlore family have attracted significant interest as they can host a huge variety of exotic phases. In order to explore the rich phase...

We have recently synthesised the novel iridocuprate IrSr2Sm1.15Ce0.85Cu2O10. This material exhibits a complex temperature dependence of the magnetic susceptibility with multiple...

Potassium TCNQ is an stoichiometric organic based salt that undergoes a spin Peierls (SP) transition at approximately 390 K. Much research has been conducted on this system in...

Continued investigation of magnetic fluctuations in the Mn-doiped chalcopyrite semiconductor ZnGeP2 is proposed using LF-MuSR depolarization rates. Due to ferromagnetism above...

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...

There is much debate about muon stopping sites within materials and in many cases knowing where the muon stops is crucial to understanding the physical properties of different...

In physics, frustration describes a situation where a system is unable to satisfy all of its internal interactions because of the geometry of its atomic structure. The most...
