An Experiment for the Measurement of the Bound β-Decay of the Free Neutron — •Wolfgang Schott, G. Dollinger, Th. Faestermann, J. M. Friedrich, J. Hartmann, R. Hertenberger, S. Paul, and A. Ulrich — Physik-Department TU-München und Sektion Physik der LMU-München, D-85748 Garching

The H hyperfine state population after the neutron bound β decay yields directly the neutrino left-handedness or a possible right-handed admixture, and small scalar (g_S) and tensor (g_T) contributions to the weak force. We present a possible setup to detect the two-body decay and to determine the hyperfine state of the resulting H atom. We will show that an improvement of the experimental limits of g_S and g_T by at least a factor of 10 seems possible.
