论文摘要
本文认为，基于$^{229} $ th核的真空紫罗兰色（VUV）范围的核光源是主要的可能性。这种核灯源可以帮助解决两个主要问题 - 激发低洼的$^{2.29m} $ th异构体以及核异构体过渡能量的精确测量。 th核光源基于植入带有大带隙的薄介电膜中的核。在通过样品中传递电流时，$^{229} $ th核对低能量异构体状态$ 3/2^+（8.19 \ pm0.12 $ eV）感到兴奋，这是在传导电子的非弹性散射过程中。随后的$^{2.29m} $ Th的自发衰减之后是在VUV范围内排放$γ$ Quanta。 thor核灯源的光度约为每1〜a的$ 10^5 $〜光子/s，每1〜a的电流和每1〜ng的$^{229} $ th。从$^{2.29m} $ TH ISOMER获得$γ$辐射的建议方案可被视为从通常的金属绝缘体 - 轴导导器（MIS）交界处的光辐射的一种核模拟。
The paper considers a principal possibility of creating a nuclear light source of the vacuum ultra violet (VUV) range based on the $^{229}$Th nucleus. This nuclear light source can help to solve two main problems -- excitation of the low-lying $^{229m}$Th isomer and precision measurement of the nuclear isomeric transition energy. The Thorium nuclear light source is based on the nuclei implanted in a thin dielectric film with a large bandgap. While passing an electric current through the sample, the $^{229}$Th nuclei are excited to the low energy isomeric state $3/2^+(8.19\pm0.12$ eV) in the process of inelastic scattering of conduction electrons. The subsequent spontaneous decay of $^{229m}$Th is followed by the emission of $γ$ quanta in the VUV range. The luminosity of the Thorium nuclear light source is approximately $10^5$~photons/s per 1~A of current and per 1~ng of $^{229}$Th. The suggested scheme to obtain $γ$ radiation from the $^{229m}$Th isomer can be considered as a kind of nuclear analogue of the optical radiation from the usual metal-insulator-semiconductor (MIS) junction.
