The first excited isomeric state of ^{229}Th possesses the lowest energy among all known excited nuclear states. The expected energy is accessible with today's laser technology and in principle allows for a direct optical laser excitation of the nucleus. The isomer decays via three channels to its ground state (internal conversion, γ decay, and bound internal conversion), whose strengths depend on the charge state of ^{229m}Th. We report on the measurement of the internal-conversion decay half…

This work carries out isotope shift calculations in Th^{+} and Th^{2+} including the specific mass shift, using a combination of configuration interaction and all-order linearized coupled-cluster methods and estimates the uncertainty of this approach.
X-ray pumping of the 229Th nuclear clock isomer
• Physics
Nature
• 2019
Active optical pumping is presented using narrow-band 29-kiloelectronvolt synchrotron radiation to resonantly excite the second excited state of 229Th, which then decays predominantly into the isomer, enabling accurate determination of the 229mTh isomer’s energy, half-life and excitation linewidth.
Excitation of ^{229m}Th at Inelastic Scattering of Low Energy Electrons.
The cross section of the time reversed process is large, and as a consequence, the probability of the nonradiative ^{229m}Th decay via the conduction electrons in metal is close to the internal conversion probability in the Th atom.
