Bound-State Beta Decay of 205Tl81 + Ions and the LOREX Project
Original language description
Stable 205Tl ions have the lowest known energy threshold for capturing electron neutrinos (νe)of Eνe >= 50.6 keV. The Lorandite Experiment (LOREX), proposed in the 1980s, aims at obtainingthe longtime averaged solar neutrino flux by utilizing natural deposits of Tl-bearing lorandite ores. To determine the νe capture cross section, it is required to know the strength of the weak transitionconnecting the ground state of 205Tl and the 2.3 keV first excited state in 205Pb. The only way toexperimentally address this transition is to measure the bound-state beta decay (βb) of fully ionized 205Tl81þions. After three decades of meticulous preparation, the half-life of the βb decay of 205Tl81þ has beenmeasured to be 291þ33-27 days using the Experimental Storage Ring (ESR) at GSI, Darmstadt. The longermeasured half-life compared to theoretical estimates reduces the expected signal-to-noise ratio in theLOREX, thus challenging its feasibility.
