Experimental, calculated and difference powder diffraction patterns and the results of crystal structure refinement for the alloy TbSn3: (a) annealed at 973 K for αTb3Sn7; (b) annealed at 1073 K for βTb3Sn7. Key differences between diffraction patterns containing α- and β-modifications of Tb3Sn7 are enlarged. |
