Title: {lambda}-neutron scattering lengths from radiative K{sup -} capture

Abstract

Radiative capture of the K{sup -} by the deuteron is examined as a reaction for measurement of {lambda}-neutron scattering lengths. Using the final-state interaction, analogous to measurements of the radiative capture of pions by deuterium, the scattering lengths of both the triplet and singlet {lambda}-n interaction can be inferred. The problem of the separation of these two fundamental parameters without and with spin information in the experiment is addressed. It is shown that a measurement of the deviation of the vector deuteron polarization asymmetry from -1 provides a direct determination of the difference of the singlet and triplet scattering lengths.
