Аннотация
The paper considers a principal possibility of creating a nuclear light source of the vacuum ultra violet (VUV) range based on the 229Th nucleus. This nuclear light source can help to solve two main problems -- excitation of the low-lying 229mTh 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 229Th nuclei are excited to the low energy isomeric state 3/2+(8.19±0.12 eV) in the process of inelastic scattering of conduction electrons. The subsequent spontaneous decay of 229mTh is followed by the emission of gamma quanta in the VUV range. The luminosity of the Thorium nuclear light source is approximately photons/s per 1A of current and per 1ng of 229Th. The suggested scheme to obtain gamma 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.
