Over the two years, the LMU Munich group has established the detection of internal conversion (IC) electrons as a successful technique to detect the Th-229 isomer. This scheme as already been used to measure the half-life of the isomer in the neutral charge state, but the really important experiment, a measurement of the isomer energy, is still pending. Such an experiment would need to measure the kinetic energy of the IC electron released in the isomer decay. The LMU team just made an important step towards this goal by laying out the theoretical foundation of such an experiment. The publication appeared yesterday in The European Physical Journal A., it is fully Open Access and can be found here.
