Advances in Muon Spin Rotation

Abstract

~1.0 Volume fraction (CH 3 0H in benzene) Volume fraction (CHCl 3 1n CH 3 0H) Figure 7 (left) Measured asymmetry of Jl + precession and corresponding residual polarization P"' as a function of the volume fraction of CH 3 0H in Ct5H 6 in two transverse magnetic fields. Circles represent data from LBL at 100 G; triangles represent data from JINR at 50 G. The dotted line indicates how the asymmetry would be expected to change if benzene gave "sponge-like" protection to CH 3 0H. (right) Similar data from LBL on CH 3 0H/CHC1 4 mixtures in 100 G fields. The dotted line here indicates how the asymmetry is expected .to vary if selective reaction by CHCI 3 were possible, or if spur scavenging by CHCI 3 occurred.

Reactions of Muonium with simple biochemical solutes in water and micelles

“…Given a suitable muon beam, one can directly observe rates of reaction of Mu and expect to see subtle kinetic isotope effects compared to 'H because of the unusually large isotopic-mass ratio. Muonium reaction rates are observed by the nuclear physics counting technique of muon spin rotation (pSR) (1,2). In this technique the species of interest (Mu) is both produced and detected, one atom at a time.…”

Isotope effects in solution: contrasts between muonium and hydrogen in reactions with acetone

“…(a) Muon spin rotation (pSR) studies Details of this technique are available elsewhere (13). It is a single particle counting method in which each muon is timed as it arrives at the sample and its decay position is timed when it is emitted.…”

Zero-field spin relaxation of the positive muon in copper

“…respect to the p spin d~rection, the histogram for a detector can be analyzed to yield the spin polarization of the p+ ensemble, projected on the detector direction, as a function of time. Several reviews of [1][2][3] the subject describe the experimental .techniques, and a more detailed discussion will be given in chapter II.…”
