通过测量由极化光子共振吸收填充的能级发射的辐射的方位角不对称性，确定了11 B跃迁的M1和E2辐射的混合比。光子散射实验是在杜克大学的自由电子激光实验室进行的，使用的是几乎单能的线性偏振光子束。的混合比推导出从测量的方位角不对称性与混合过渡的角分布的计算的比较。
The mixing ratios of M 1 and E2 radiation for transitions in 11 B have been determined by measuring the azimuthal asymmetry of the radiation emitted from levels populated by resonant absorption of polarized photons. The photon-scattering experiments were carried out at the Free-Electron Laser Laboratory at Duke University using nearly monoenergetic and linearly polarized photon beams. The mixing ratios were deduced from a comparison of the measured azimuthal asymmetries with calculations for the angular distributions of mixed transitions.
