Alternative approach to populate and study the 229Th nuclear clock isomer

RADIOACTIVITY 229mTh(IT)[from β- decay of 229Ac produced in U(p, X), E=1.4 GeV reaction, via a laser ion source at ISOLDE-CERN]; proposed an alternative method to produce the low-energy isomer in 229Th at 7.6 eV after the implantation of 229Ac ions in a large-band gap CaF2 host. Discussed benefits of using 229Ac ion beam in contrast to common use of α decay of 233U for the study of half-life and excitation energy of the 229Th isomer. Preparatory experiments, testing key ingredients of this concept, were conducted at ISOLDE-CERN.
