Introduction. In th is paper, w e derive a best possible decay ra te of sca tte ring sta tes for th e Schr6dinger opera to r H=-4 -1 -V (x ) i n L 2 (R n ) (n_2 ) w ith a long-range potential. W e impose the following assumption on V(x): V(x) is a real-valued C-function on R n and fo r some constant so >0 (A) D'IV(x)=0(I x a s lxi 4 co for a ll multi-index a. Here for a=(a i , ••• , an ), Dg= -(alaxi)"••• (alaxn)an a n d a i =cYl+ ••• +an. A s is well-known, if f belongs to the absolutely continuous subspace for H, the local position probability of ei tH decays in the sense that fo r any R >0
