Alpha spectrometric characterization of thin U sources for Th production

Raphael Haas, Michelle Hufnagel, Roman Abrosimov +6

Four different techniques were applied for the production of U alpha recoil ion sources, providing Th ions. They were compared with respect to a minimum energy spre…

Development of a recoil ion source providing slow Th ions including Th in a broad charge state distribution

Raphael Haas, Tom Kieck, Dmitry Budker +7

Ions of the isomer Th are a topic of high interest for the construction of a "nuclear clock" and in the field of fundamental physics for testing symmetries of nature. They…

Catching, trapping and in-situ-identification of thorium ions inside Coulomb crystals of Ca ions

Felix Stopp, Karin Groot-Berning, Georg Jacob +7

Thorium ions exhibit unique nuclear properties with high relevance for testing symmetries of nature, and Paul traps feature an ideal experimental platform for performing high preci…

The concept of laser-based conversion electron Mössbauer spectroscopy for a precise energy determination of Th

Lars C. von der Wense, Benedict Seiferle, Christian Schneider +13

Th is the only nucleus currently under investigation for the development of a nuclear optical clock (NOC) of ultra-high accuracy. The insufficient knowledge of the first nu…

Trapping and sympathetic cooling of single thorium ions for spectroscopy

Karin Groot-Berning, Felix Stopp, Georg Jacob +7

Precision optical spectroscopy of exotic ions reveals accurate information about nuclear properties such as charge radii and magnetic and quadrupole moments. Thorium ions exhibit u…
