ALCs investigation of the polymer PTAA (chain length = 80)
This proposal aims to study the avoided level crossing resonances (ALCs) of the amorphous polymer PTAA, with chain length 80. Previous measurements on PTAA have studied a... -
Probing the spin dynamics in the pseudo-quaternary Y1-xErxNi2B2C compounds
Our uSR measurements on superconducting Y1-xErxNi2B2C shows a slowing of the Er spin dynamics upon cooling to 2.5 K, but the depolarisation rate does not critically diverge and... -
Detailed temperature dependence of the low-field ALC in TMS-Pentacene
We wish to investigate the evolution of the low-field ALC peaks with temperature of TMS-Pentacene, so we can extract the temperature dependent electron spin relaxation rate. Our... -
Probing the [FeFe]-hydrogenase using muon spectroscopy
During our previous experiment on HiFi (RB1320541) we measured the ALC spectrum of the Fe2(µ-pdt)(CO)4(PMe3)2 model hydrogenase complex over multiple temperatures. The spectra... -
Probing the [FeFe]-hydrogenase subsite using muon spectroscopy
Previous ALC measurements of the Fe2(pdt)(CO)4(PMe3)2 and [Fe2(pdt)(CO)4(CN)2]2- (referred to as 1 and 2) model hydrogenase subsites have yielded some intriguing results (RB... -

Repolarisation and level crossing resonance will be studied for several different oxalate compounds where muon radical states are known to be formed. Such compounds form a... -
ALC muon spectroscopy of antioxidants
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... -
Validating a new theoretical method for predicting the HFC of small molecular...
ALC is the best technique to characterize muoniated radicals, that are produced by muonium bonding to unsaturated bonds in molecules. Good agreement between data from ALC and... -
