Abstract
Point contact spectroscopy results obtained along the CuO planes an or iented LaSrCuO samples are presented. Both Andreev and tunneling conta cts have been studied, up to 100 meV. The results are interpreted with in the framework of a recent theory of inelastic transport through nor mal metal-superconductor interfaces. and both types of contacts are co nsistent with this theory. They point clearly to the electron-phonon i nteraction as the source of this inelastic scattering and of supercond uctivity in this cuprate.
