摘要：

The structure of two polymorphs of manganese dioxide, lambda-MnO2 and gamma-MnO2 and the spinel oxide LiMn2O4 have been refined by Rietveld analysis of powder neutron diffraction data. lambda-MnO2, Fd3m, a = 8.0639(3) Angstrom, R(Bragg) = 1.81%, gamma-MnO2, Pnam, a = 9.3229(11) Angstrom, b = 4.4533(7) Angstrom, c = 2.8482(3) Angstrom, R(Bragg) 1.34% and LiMn2O4, Fd3m, a = 8.2468(2) Angstrom, R(Bragg) = 2.33%.
