| Abstract: | Low energyN¯N scattering is reanalyzed using the new data on annihilation cross-sections from CERN 1], the¯np-absorption measurement from BNL 2] and the annihilation width of the 2p state in antiprotonic hydrogen 3]. Imposing the condition that the imaginary part of the effective range is negative we find low energy scattering parameters which interpolate between the existing ITEP 4] and CERN/Heidelberg 5] values.Supported by the BMFT-grant 06 HD 756 |
