dc.description.abstract© 2019 American Physical Society.In the paper, a unique process of the decay of the Th229m(3/2+,8.28±0.17 eV) low-energy nuclear isomer via the internal conversion (IC) channel on Rydberg states is considered for the first time. The Rydberg atom Th+229m+eRy- is a unique object where IC is possible exclusively on the Rydberg electron eRy-. It is shown that in the Th4+229m+eRy- system (a) IC on the electron states with relatively small values of the principal quantum number n and the orbital moment l is practically completely suppressed, (b) IC probability, WIC, on the ψns1/2(r) states is proportional to |ψns1/2(0)|2 and can be related with the energy of the hyperfine interaction of the Rydberg electron with the nucleus, (c) WIC decreases rapidly with the increase of n in the range from 10 to 50, and in the range n 150WIC changes as const/n3 typical for hydrogen-like ions, and (d) at n≈10-30, WIC as a function of l has a characteristic "knee" between l=3 and l=4, i.e., a decrease of three orders of magnitude in WIC due to the qualitative change in the ratio between the centrifugal and shielding potentials.
