| 2 | X-Ray and Neutron Diffraction Studies on Thermal Parameters of Thalous Bromide显示文摘Thermal parameters of TIBr were determined using both X-ray and neutron diffraction techniques. The data was analysed by Rietveld profile refinement procedure. From the neutron diffraction data, due to weak odd-order reflections, it was not possible to determine the individual thermal parameters. The X-ray diffraction measurements yielded BT1=0.296(5) nm2 and BBr=0.162(5) nm2. The overall isotropic value, B was 0.252(7) nm2 which is in good agreement with B=0.230(8) nm2 obtained from present neutron diffraction measurements. The present values are also in good agreement with theoretical estimates obtained from the shell models. | J.Bashir R.T.A.Khan T.Ikeda KenichiOhshima | 2003 | Journal of Materials Science & Technology2003，19，2： | 0 |
