Complete Nuclear Dipolar Line Shapes for High Transverse Field μSR

As illustrated by the calculated line shapes, dipolar broadening at the muon site is highly sensitive to the direction of the external magnetic field. Judicious choice of the external field direction can be used to minimize dipolar broadening and departures of the line shape from a gaussian character. The calculation is a valuable tool to predict field dependence for a given muon site. Alternatively, it may be used to determine the muon site from experimental data obtained at various field orientations. In situations where the line shape is not well fit by a Gaussian and/or where the muon induces lattice distortion, the calculation is a valuable tool to better fit the μSR data.
