Russian physicist Eugene Tkalya of the Research Institute of Nuclear Physics Skobel'tsyn at Lomonosov Moscow State University proposed a scheme for a nuclear laser operating in the visible range. The article appeared in the scientific journal Physical Review Letters, and its summary results in Physical Review Focus. Preprint of the article can be found here (English).
Laser on the "nuclear world" scientists call a laser, in which photons are emitted during the transition to an excited state of atomic nuclei directly, rather than electrons. Theoretically, these lasers can be a source of coherent gamma-radiation (Graeser), but many physicists doubt the possibility of creating such devices in practice.
As part of his new job Tkalya demonstrated the theoretical possibility of a laser at a nuclear world, which, however, is still operating in the optical range. As a working body, he suggests using LiCaAlF6 with some inclusions of thorium atoms 229Th. Feature of thorium in the fact that its nucleus has an excited state whose energy is very different from the excited levels of electron shells of atoms.
Calculations show that for sufficiently strong magnetic (or electric) field of thorium atoms begin to emit photons. This gives rise to coherent radiation in the optical range. According to the experts. new work is an important step towards the creation of Graeser.
