摘要：

讨论了两种介质界面上的跃迁辐射过程$ν\to νγ$。介质实现了诱导有效中微子光子顶点和修改光子色散关系的双重目的。当这些量中的至少一个在不同的介质中具有不同的值时，跃迁辐射发生。我们提出了一个结果的概率的过渡辐射，这是准确的和分析。对于MeV的$E_ν=1$中微子穿过聚乙烯-真空界面，跃迁辐射几率约为$10^{-39}$，能量强度（沉积）约为$10^{-34}$ eV.在中子星表面，跃迁辐射几率可能是$\sim 10^{-20}$。我们在三个数量级上的结果比以前的计算结果大。

英文摘要：

We discuss the transition radiation process $ν\to νγ$ at an interface of two media. The medium fulfills the dual purpose of inducing an effective neutrino-photon vertex and of modifying the photon dispersion relation. The transition radiation occurs when at least one of those quantities have different values in different media. We present a result for the probability of the transition radiation which is both accurate and analytic. For $E_ν=1$MeV neutrino crossing polyethylene-vacuum interface the transition radiation probability is about $10^{-39}$ and the energy intensity (deposition) is about $10^{-34}$eV. At the surface of the neutron stars the transition radiation probability may be $\sim 10^{-20}$. Our result on three orders of magnitude is larger than the results of previous calculations.}
