A NEW APPROACH IN NUCLEAR-QUADRUPOLE INTERACTION DATA-ANALYSIS - CROSS-CORRELATION

The signal to noise ratio in hyperfine spectra split by nuclear quadru pole interactions can be improved significantly by cross correlating e xperimental with theoretical spectra, especially for higher spins. In part I of the paper we present all technical details of this new appro ach and give examples for half integer and integer spins. In part II w e elucidate the difficulties which arise in the attempt to reconstruct distribution functions of the largest component of the electric held gradient tensor V-ZZ and the asymmetry parameter eta from experimental line positions and profiles.
