Let H =&( 2 Â2) 2+V(x) be a Schro dinger operator on R n , with smooth potential V(x) Ä + as |x| Ä + . The spectrum of H is discrete, and one can study the asymptotic of the smoothed spectral density We shall investigate the case where E is a critical value of the symbol H of H and, extending the w
