摘要：

A modified Fisher information, the sum of the one-electron Fisher information, is proposed. It is shown that the modified Fisher information is the original Fisher information plus a sum of differences of quantum and classical variances. A generalization of the Stam's inequality is derived. It is argued that Fisher information provides a measure of steric effect. (c) 2007 Elsevier B.V. All rights reserved.
