Abstract The radioisotope thorium-229 (229Th) is renowned for its extraordinarily low-energy, long-lived nuclear first-excited state. This isomeric state can be excited by vacuum ultraviolet (VUV) lasers and 229Th has been proposed as a reference tra

Abstract We have grown $$^{232}$$ 232 Th:CaF $$_2$$ 2 and $$^{229}$$ 229 Th:CaF $$_2$$ 2 single crystals for investigations on the VUV laser-accessible first nuclear excited state of $$^{229}$$ 229 Th, with the aim of building a solid-state nuclear c

Chemical reactions with ultracold atoms and ions are explored so far with the atom–ion interactions. Here the authors discuss spin-exchange process and show that the spin state of an ensemble of neutral Rb atoms can be used to control the final spi

Experiments in which ultra-cold neutral atoms and charged ions are overlapped, constitute a new field in atomic and molecular physics, with applications ranging from studying out-of-equilibrium dynamics to simulating quantum many-body systems. The ho

The original version of this Article contained an error in the third sentence of the first paragraph of the ‘Spin polarizing the Sr+ ion with ultracold atoms’ section of the Results, which incorrectly read ‘The Langevin collision rate is 1.’

Physical Review A
The electronic defect states resulting from doping $^{229}\mathrm{Th}$ in ${\mathrm{CaF}}_{2}$ offer a unique opportunity to excite the nuclear isomeric state $^{229\mathrm{m}}\mathrm{Th}$ at approximately 8 eV via electronic bridge mechanisms. We co

We present 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. The energy resolution of ∼10 eV, together with exceptional gain linearity, allows us to

When Th nuclei are doped in ${\mathrm{CaF}}_{2}$ crystals, a set of electronic defect states appear in the crystal band gap which would otherwise provide complete transparency to vacuum-ultraviolet radiation. The coupling of these defect states to th
