Negative Moun Spin Rotation

Abstract

The possibility of using the muon spin rotation for solid-state studies is discussed. Some preliminary experimental results of negative muon spin rotation experiments related to g-factor measurements in diamagnetic metals and relaxation phenomena in transition metals are presented.

Muon spin resonance — A variant of magnetic resonance

“…2). A further typical behavior is the stretched exponential GN(t ) = exp(-(2t) ~) (11) as is often found in spin glasses [19]. For more complex cases, Gll(t) is not available in analytical form and has to be computed numerically.…”

“…In this way, the alchemists' old dream of a conversion of mercury to gold becomes true -unfortunately the negative muon gets absorbed by the nucleus, which leads to its disintegration, so that the new source of wealth turns out to be a very futile one. Although it is useful in principle asa probe in matter, the disadvantages of polarization loss during the cascade and of the radiation damage due to the many Auger electrons created in the course of this process are so severe that only a very limited number of ~t--applications have appeared in literature [11,12].…”

Muonium Chemistry—A Review

“…Indeed, the negatively charged muon acts exactly like a heavy electron, forming muonic atoms in which the μ' orbits tightly about the nucleus, well inside any electronic orbits (17,18,19). Muonic hydrogen, consisting of a proton and a μ', chemically resembles a neutron and is a poor analogue of atomic hydrogen in any conventional chemical sense.…”

Advances in Muon Spin Rotation

“…This does not mean that we consider Jl-sR unimportant. On the contrary, while the Jl-sR technique is more difficult because of small muon polarizations in the final state and the dominance of muon capture over decay for high Z, it may soon provide very important information complementary to that discussed here (3)(4)(5). However, the overwhelming majority of 11SR work is still being done with positive muons, and this review reflects that fact.…”
