CRYSTAL STRUCTURE OF 3-tert-BUTYL- PYRAZOLO[5,1-с][1,2,4]TRIAZINE-3,4-DIYL DICARBOXYLATES
Autor: L. M. Mironovich, D. S. Koltun, Sergey M. Ivanov
Publikováno v: Journal of Structural Chemistry
By single crystal X-ray diffraction the structures of (trans-)7-R1-8-methyl-3-tert-butyl-3,4-dihydropyrazolo[5,1-с][1,2,4]triazine-3,4-diyl dibenzoates 3а, 4а (R1 = H, Br) and diacetate 3b (R1 = H) are studied for the first time. The compounds are

Theoretical nuclear physics
Autor: D. S. Koltun, J.B. French
This report summarizes progress during the past year in the following areas of research: Pion double charge exchange, including studies of the contribution of meson exchange currents and the roles of chiral symmetry and of vector mesons. The possibil

Linear Relations Among Nuclear Energy Levels
Autor: D S Koltun
Publikováno v: Annual Review of Nuclear Science. 23:163-192
The linear spectroscopic factors for nuclear spectra associated with simple configurations are investigated from two points of view, showing two ways in which effective interactions are treated in shell model theory. First the interactions are consid

Statistical theory of pion-nucleus reactions near the (3,3) region
Autor: D. Agassi, D. S. Koltun
Publikováno v: AIP Conference Proceedings.
Pion‐nucleus scattering for bombarding energies in the (3,3) region is described in terms of a transport equation, following the propagation, diffusion and true‐absorption of the Δ‐isobar.

Nuclear structure theory
Autor: D. S. Koltun, J.B. French
This report summarizes progress during the past ten months in the following areas of research: pion double charge exchange reactions, including a theory of the isotensor term in the pion-nucleus optical potential, and a study of meson exchange contri
