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…

Nuclear Charge Radii of ^{229}Th from Isotope and Isomer Shifts.
TLDR
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
TLDR
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.
TLDR
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.
Energy of the 229Th nuclear clock transition
TLDR
The method combines nuclear and atomic physics measurements to advance precision metrology, and the findings are expected to facilitate the application of high-resolution laser spectroscopy on nuclei and to enable the development of a nuclear optical clock of unprecedented accuracy.
Toward an energy measurement of the internal conversion electron in the deexcitation of the Th229 isomer
The first excited isomeric state of Th-229 has an exceptionally low energy of only a few eV and could form the gateway to high-precision laser spectroscopy of nuclei. The excitation energy of the
Measurement of the ^{229}Th Isomer Energy with a Magnetic Microcalorimeter.
TLDR
A measurement of the low-energy (0-60 keV) γ-ray spectrum produced in the α decay of ^{233}U using a dedicated cryogenic magnetic microcalorimeter and four complementary evaluation schemes is presented.
Attempt to optically excite the nuclear isomer in Th229
We aim to perform direct optical spectroscopy of the $^{229}\mathrm{Th}$ nuclear isomer to measure its energy and lifetime, and to demonstrate optical coupling to the nucleus. To this end, we develop
Alternative approach to populate and study the Th229 nuclear clock isomer
A new approach to observe the radiative decay of the $^{229}$Th nuclear isomer, and to determine its energy and radiative lifetime, is presented. Situated at a uniquely low excitation energy, this
The theory of direct laser excitation of nuclear transitions
A comprehensive theoretical study of direct laser excitation of a nuclear state based on the density matrix formalism is presented. The nuclear clock isomer $^{229\text{m}}$Th is discussed in detail,
Laser spectroscopic characterization of the nuclear-clock isomer 229mTh
TLDR
The laser spectroscopic investigation of the hyperfine structure of the doubly charged 229mTh ion and the determination of the fundamental nuclear properties of the isomer, namely, its magnetic dipole and electric quadrupole moments, as well as its nuclear charge radius are presented.
