In the recently suggested non-standard, quasi-molecular mechanism of recombination, the presence of neighboring proton increases the ionization energy and decreases the final recombination rate of hydrogen. Both these two effects can lead to the larger value of the present expansion rate of the universe obtained using CMB data and standard cosmological model, and thus are able to reduce or resolve the Hubble tension problem. We note also that due to the quasi-molecular channel the recombination began earlier, what potentially can solve the sigma-eight tension, since the CMB-predicted value of the late matter density will be decreased.

重组的准分子机制能否降低哈勃张力？

在最近提出的非标准、准分子复合机制中，相邻质子的存在会增加电离能并降低氢的最终复合率。这两种效应都可以导致使用CMB数据和标准宇宙学模型获得的宇宙当前膨胀率的较大值，从而能够减少或解决哈勃张力问题。我们还注意到，由于准分子通道，重组开始得更早，这可能可以解决 sigma-8 张力，因为后期物质密度的 CMB 预测值将降低。
