Nonradiative DKR processes: revisiting the theory. III. Multimode approaches
摘要：
我们概述了一种方法，用于处理松弛的光激发NaI F中心在一个单一的有效频率沿多模坐标。通过耦合到一个T_{1u}振动模式的2s-2 p混合也进行了讨论，得到了乐观的结论。平衡非辐射去激发率估计和相互振动弛豫，以评估非平衡DKR去激发的效率进行比较。他们表明，前者是没有竞争力的，由于大量的声子交换。
英文摘要：
We outline a method for dealing with the relaxation of optically excited NaI F centers in terms of a single effective frequency along a multimode coordinate. The 2s-2p mixing through coupling to a T_{1u} vibrational mode is also discussed with optimistic conclusions. Equilibrium nonradiative deexcitation rates are estimated and compared with intervibrational relaxations so as to assess the efficiency of the nonequilibrium DKR deexcitation. They show the former not to be competitive, due to the large number of phonons exchanged.
