CALCULATION OF THE AVOIDED LEVEL-CROSSING MUON SPIN-RESONANCE RESPONSE FOR VARIOUS STOCHASTIC MOTIONS USING MONTE-CARLO METHODS

Spectral simulations of the dynamic avoided level-crossing muon spin r esonance response, calculated using Monte Carlo methods, are presented , This work is exclusively concerned with the band associated with the Delta M = 1 transition, the form of which is found to be highly depen dent upon the nature of the dynamic behaviour of the radical. Various types of stochastic motion are considered, It is shown that spherical averaging of the muon anisotropy instigates a broadening of the resona nce and ultimately, the loss of any meaningful intensity. Any motion w hich gives rise to residual anisotropy will be manifested by residual intensity at the central band position, Spectral simulations are compa red with previous simulations, calculated using the stochastic Liouvil le formalism, and related to experimental data.
