Excitation of the anomalously low lying nuclear isomer ^{229m}Th(3/2^{+},8.28±0.17  eV) in the process of inelastic electron scattering is studied theoretically in the framework of the perturbation theory for the quantum electrodynamics. The calculated cross sections of ^{229m}Th by the extremely low energy electrons in the range 9-12 eV for the Th atom and Th^{1+,4+} ions lie in the range 10^{-25}-10^{-26}  cm^{2}. Being so large, the cross section opens up new possibilities for the effective… Expand

Lifetime Measurement of the ^{229}Th Nuclear Isomer.
TLDR
The measurement of the internal-conversion decay half-life of neutral ^{229m}Th has been measured, which is in the range of theoretical predictions and gives further support for an internal conversion coefficient of ≈10^{9}, thus constraining the strength of a radiative branch in the presence of internal conversion.

TLDR
The reduced magnetic dipole and electric quadrupole transition probabilities for the radiative decay of the ^{229}Th 7.8  eV isomer to the ground state are predicted within a detailed nuclear-structure model approach and support new directions in the experimental search of the^{229]Th transition frequency for the development of a future nuclear frequency standard.
