The Manitoba II high resolution mass spectrometer has been used to measure precise values for the spacings of four mass doublets in the mass spectra of Tl and Pb chlorides. Our new data are combined with other precise experimental data to derive an improved value for the 205Pb-205Tl atomic mass difference, viz., 51.06±0.51 keV. This value agrees with most previous data, identifies one inconsistent datum and substantially improves the precision of this mass difference. This improvement in precision, in turn, reduces the uncertainty in one aspect of the derivation of the cross section for the neutrino capture reaction, v+205Tl → 205Pb+erme−. This reaction has been proposed as the possible basis for a favourable solar neutrino detector. |
