Nonradiative Excitation of the Muonic Atom exp 238 U as an Inverse Conversion Process

摘要

The probabilities of nonradiative nuclear excitation are calculated for different muon transitions in the muonic atom exp 238 U. Microscopic nuclear wave functions, obtained within the quasiparticle-phonon nuclear model, and the muonic conversion coefficients have been used. The probability of nonradiative nuclear excitation for the muonic transitions 2p implies 1s and 3p implies 1s has been found to be equal to 0.3. It is predicted that nonradiative E3 transitions 3d implies 2p can take place with the probability 0.08-0.10. The dynamic effect of nuclear structure on the probability of nonradiative nuclear excitation is taken into account. The estimates of exp 238 U fissility fission branching at nonradiation transitions are also obtained. (Atomindex citation 14:785635)
