摘要：

We present a new analysis of the electron capture mechanism in polar molecules, based on von Neumann's theory of self-adjoint extensions. Our analysis suggests that it is theoretically possible for polar molecules to form bound states with electrons, even with dipole moments smaller than the critical value D-0 = 1.63 x 10(-18) esu cm. We argue that the quantum mechanical scaling anomaly is responsible for the formation of these bound states. (c) 2008 Elsevier B.V. All rights reserved.
