Defect assignment of the clock site in
Daniel A. Rehn, Harry W. T. Morgan, Harris E. Mason +6
The paper reexamines which crystal defect hosts the 229Th nucleus in CaF2, showing that an isolated Th4+ substituting for Ca2+ with two nearby fluoride interstitials best explains…

Ab initio calculations of Th band-to-band internal conversion rate in ThO
Udeshika C. Perera, H. B. Tran Tan, H. W. T. Morgan +3
We present an ab initio calculation of the band-to-band internal-conversion rate of the eV isomeric transition in ThO. Because the nucl…
