Abstract

Using the technique of muon spin relaxation (µSR), repolarisation curves are determined following the deposition of positive muons in samples of apoferritin over the temperature range 50 K to 270 K, and ferritin over the temperature range 15 K to 280 K. Evidence is found for a muonium-substituted species common to both apoferritin and ferritin. In apoferritin at 270 K an estimate for A′, the reduced isotropic muon–electron hyperfine coupling constant, is 168±39 MHz. In ferritin at 280 K the value for A′ is 164±37 MHz.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
