摘要：
Renormalization-Group theoretic approach to disorder induced electron localization is reconsidered. It is suggested that there is a naturally occurring lower wavevector cut-off in the problem such that one should eliminate the long-wavelength degrees of freedom in favour of the shorter ones, contrary to the usual procedure. One, indeed, obtains in this way a physical fixed point in that (Formula presented). © 1978, Indian Academy of Sciences. All rights reserved.
