在一对最近的论文（Ziebell等人2008 Phys.Plasmas 15 032303，2008 Plasma Phys.Control. Fusion 50 085011），在弱湍流理论的背景下，显示了由尾部凸起不稳定性产生的朗缪尔湍流不会导致二维朗缪尔凝聚（或在长波长区域中波能量和动量的积累）。目前的分析发现，它是重要的，包括自发散射离开朗缪尔湍流的电子，这是忽略了在习惯的文献相比，类似的过程涉及离子，为了恢复凝聚的朗缪尔波在两个维度。
In a pair of recent papers (Ziebell et al 2008 Phys. Plasmas 15 032303, 2008 Plasma Phys. Control. Fusion 50 085011) it was shown, within the context of weak turbulence theory, that the Langmuir turbulence generated by the bump-in-tail instability does not lead to Langmuir condensation (or accumulation of wave energy and momentum in the long-wavelength regime) in two dimensions. The present analysis finds that it is important to include the spontaneous scattering off Langmuir turbulence of the electrons, which is ignored in the customary literature when compared with a similar process involving ions, in order to recover the condensation of Langmuir waves in two dimensions.
