• Andreev reflection in 21 one-dimensional interacting electron gas coupled with a bulk super-condtrctor is studied theoretically. In the case of we?xk irxteracl,ion we calctnlate the renorrnalizedAndreev-reflection amplitude using a poor lTl2trl'S renorrrraliza,Lion grotnp approach, taking ac-cottnt of both the forwar'd and backward scatterings dtre to the electron-electron interaction.The conductance as a function of teznperatvxre is olctained for arbitrary strength of the barrierpotential at the norrnal-supercondttctor interf?tce. XX7e show that the restrlting tempen'?rture de-pendence is stronger than that of single-barrier conductance in the one-diztaensional interactingelectron gas. It is also shoxvn that any logarithmic temperature dependence does not appear inthe Andreev condtmctance despite the presence of' the backward scattering.
