Abstract
For zero- or longitudinal-field μSR, instead of assuming a Gaussian field distribution at the muon, the dipole field distribution at the candidate muon site(s) can be found numerically, using the crystal structure of the particular material. Examples show that, while often not well approximated by Gaussians, local field distributions can still be approximated by simple forms. The associated Kubo-Toyabe zero-field relaxation functions are discussed.
