PROCESSES OF THE NUCLEAR ISOMER TH-229M(3 2(+), 3.5+/-1.0EV) RESONANTEXCITATION BY OPTICAL PHOTONS/

The excitation processes of the low energy isomeric level in nucleus T h-229 by optical photons are investigated for different values of rela tions between energies of nuclear transition and photons. The role of the atomic shell, which ''works'' as electron bridge, is considered. T he cross-sections of the resonance nuclear excitation by laser beam (t he narrow line) and by special lamp (the wide line) ale calculated The possibilities of experimental researches are discussed.
