Determination of Nuclear Hyperfine Structure of α-Fe2O3 From its Quantum Beats.

Nuclear resonant scattering quantum beats (QBs) spectrum reflects the interference information between all the possible energy transitions once which makes it difficult to analyze. Here we propose a new analysis method that can give the hyperfine structure directly from the QBs. As a case study, we analyzed QBs of a hematite sample at several temperature points across its Morin temperature. We observed that the transverse between the excited energy transitions which is accordance with the results obtained by the conventional MS method. [ABSTRACT FROM AUTHOR]
