Comprehensive study of electronic structure of Th1+ in the isomer energy region
Using 2-photon resonant laser spectroscopy, the PTB team identifies 166 previously uncharted electronic states of the Th1+ ion in the energy range between 7.8 and 9.8 eV. The observed levels can be relevant for the excitation or decay of the 229mTh isomeric nuclear state which lies in this energy range. The high density of electronic levels promises a strongly enhanced electronic bridge excitation of the isomer in 229Th. Read more on arXive.
