Adiabatic Fast Passage Spin Manipulation Measurements in Solid Polarized Targets

D. Keller, K. Nakano, M.F. Hossain, N.G. Vismith

Adiabatic fast passage reverses polarization rapidly in solid targets while a new lineshape analysis extracts vector and tensor components from non-Boltzmann NMR spectra.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

The main advances are threefold: (i) new measurements of AFP efficiency in irradiated 15NH3, irradiated 14ND3, and butanol systems; (ii) a joint manipulated-lineshape analysis that extracts vector and tensor polarization components from AFP-manipulated NMR spectra including non-Boltzmann half-flip states; (iii) an efficiency study of irradiated 15NH3 showing strong dependence on initial polarization.

C2weakest assumption

The joint manipulated-lineshape analysis correctly extracts vector and tensor components without post-hoc adjustments or unaccounted systematic effects in the NMR spectra of non-Boltzmann states.

C3one line summary

AFP achieves high-efficiency spin flips in polarized targets with initial-polarization dependence, and a new joint lineshape analysis extracts vector and tensor components from non-Boltzmann NMR spectra.
