论文摘要
在本文中，以量子力的基础研究了紧凑型恒星中紧凑型恒星中的pynon核反应。多种内部反射的形式主义被推广用于分析，这是为核腐烂和捕获高精度和测试捕获的。对于所选的反应$^{12} $ C + $^{12} $ C = $^{24} $ mg，我们找到以下内容。对肺核反应的量子研究需要对内部核区域中的量子通量进行完整分析。这将pycnoncorlear反应的速率和数量降低了1.8次。这导致出现新状态（称为quasibound状态），其中复合核系统的形成具有最大概率。如图所示，这种状态的最小能量略高于pycnon核反应中晶格位点中零点振动的能量，但是在quasibound状态下形成复合系统的概率基本上大于零点振动状态下的相应概率。因此，有一种理解的是，在准圆形状态下的反应速率更可能，而不是零点振动的状态。这可能导致估计恒星核反应速率的基本变化。
Pycnonuclear reactions in the compact stars at zero temperatures are studied on quantum mechanical basis in the paper. Formalism of multiple internal reflections is generalized for analysis, that was developed for nuclear decays and captures by nuclei with high precision and tests. For the chosen reaction $^{12}$C + $^{12}$C = $^{24}$Mg, we find the following. A quantum study of the pycnonuclear reaction requires a complete analysis of quantum fluxes in the internal nuclear region. This reduces rate and number of pycnonuclear reactions by 1.8 times. This leads to the appearance of new states (called as quasibound states) where the compound nuclear system is formed with maximal probability. As shown, minimal energy of such a state is a little higher than energy of zero-point vibrations in lattice sites in pycnonuclear reaction, however probability of formation of compound system at the quasibound state is essentially larger than the corresponding probability at state of zero-point vibrations. Hence, there is a sense to tell about reaction rates in such quasibound states as more probable, rather than states of zero-point vibrations. This can lead to the essential changes in estimation of the rates of nuclear reactions in stars.
