用共振X射线散射（RXS）技术首次在零磁场下观察到了反铁四极（AFQ）有序化合物CeB_6的四极序参量q（Q）=（1/2，1/2，1/2）.在Ce L-3边的2 p →> 5d偶极跃迁能处观察到RXS。利用这种RXS技术观察AFQ态的纯序参量，首先确定了第II相的磁相图。
Under zero magnetic field, a quadrupolar order parameter at q(Q) = (1/2, 1/2, 1/2) in a typical antiferro-quadrupole (AFQ) ordering compound CeB6 has been observed for the first time by means of a resonant X-ray scattering (RXS) technique. The RXS is observed at the 2p --> 5d dipole transition energy of the Ce L-3-edge. Using this RXS technique to observe the pure order parameter of the AFQ state, the magnetic phase diagram of Phase II is first determined.
