Phys. Rev. Lett. 85, 4446–4449 (2000)Measurement of Gamow-Teller Strength for 176Yb→176Lu and the Efficiency of a Solar Neutrino DetectorReceived 9 June 2000; published in the issue dated 20 November 2000 We report a 0° 176Yb(p,n)176Lu measurement at IUCF where we used 120 and 160 MeV protons and the energy dependence method to determine Gamow-Teller (GT) matrix elements relative to the model independent Fermi matrix element. The data show that there is an isolated concentration of GT strength in the low-lying 1+ states making the proposed Low Energy Neutrino Spectroscopy detector (based on neutrino captures on 176Yb) sensitive to pp and 7Be neutrinos and a promising detector to resolve the solar neutrino problem. © 2000 The American Physical Society URL:
