Description	A study using resonant x-ray scattering at the Mn K edge has been carried out on a Bi0.63Sr0.37MnO3 single crystal. This compound undergoes a metal - insulator phase transition to the so- called charge ordered ( CO) state at about 530 K. Strong resonance signals were observed at room temperature as the energy was tuned through the Mn K edge for several superstructures of the CO phase. The energy, polarization and azimuth angle dependences agree with a checkerboard ordering in the ab plane of manganese atoms of two types, in terms of their different local geometrical structures. One of the sites is anisotropic - a tetragonal distorted oxygen octahedron - and the other is isotropic - a nearly undistorted one, as observed for Bi0.5Sr0.5MnO3 and other half- doped manganites. This result indicates that the checkerboard pattern is strongly stable and extends to doping concentrations x < 0.5. No superstructures corresponding to the doubling of the c axis were detected. Intermediate valence states lower th A study using resonant x-ray scattering at the Mn K edge has been carried out on a Bi0.63Sr0.37MnO3 single crystal.
