已测量并计算了镱 (...6s6p 3PJ) 能级的微分截面 (DCS) 和电子碰撞相干参数 (EICP)。 (...6s6p 3P1) 和 (...6s6p 3P2) 水平的 DCS 在 10、20 和 40 eV 的碰撞能量下测定。 (...6s6p 3P1) 中间耦合能级的 EICP 在 20 和 40 eV 的碰撞能量下测定。计算是在酉化畸变波近似中进行的。测量是在带有 EICP 的交叉光束装置中进行的，使用激光激发到 3P1 能级的原子的超弹性散射技术进行测量。
Differential cross sections (DCS) and electron impact coherence parameters (EICP) have been measured and calculated for the (...6s6p 3PJ) levels in ytterbium. DCS for the (...6s6p 3P1) and (...6s6p 3P2) levels were determined at collision energies of 10, 20 and 40 eV. EICP for the (...6s6p 3P1) intermediate-coupled level were determined at collision energies of 20 and 40 eV. Calculations were made in the unitarized distorted-wave approximation. Measurements were made in a crossed-beam apparatus with EICP measured using the technique of superelastic scattering from atoms laser-excited into the 3P1 level.
