The inverse [beta] decay [sup 205]Tl([nu],[ital e])[sup 205]Pb can be used to investigate the solar neutrino flux averaged over the last several million years. The inverse [beta] decay proceeds dominantly via the 2.3 keV level of the [sup 205]Pb and an accurate estimate of the cross section depends on our knowledge of the structure of the 2.3 keV level. We have made the first measurement of the half-life for the decay of the 2.3 keV level to the [sup 205]Pb ground state. Our result is [ital T][sub 1/2]=24.2[plus minus]0.4 [mu]s and can be used to improve our knowledge of the structure of the two [sup 205]Pb states.
