Finite-size scaling for critical conditions for stable quadrupole-bound anions.

We present finite-size scaling calculations of the critical parameters for binding an electron to a finite linear quadrupole field. This approach gives very accurate results for the critical parameters by using a systematic expansion in a finite basis set. The model Hamiltonian consists of a charge Q located at the origin of the coordinates and k charges -Q/k located at distances R(i), i=1, em ...

Bi-dipole-bound anions

The possibility of electron binding by a molecule with two polar ends, each of which is capable of electron binding, is studied using electronic structure methods. The destabilizing effects of each dipole on the ability of the other dipole to bind an electron as well as the through-bond splitting between the g and u anion states are examined. In addition, the ability of the two polar ends to bi...

I-38: Search for Genetic Causes of Male Infertility

Background: We are convinced that better infertility treatment will only be achieved with a better under understanding of the molecular mechanisms specific to each patient. To that effect we want to indentify genes involved in male infertility. Materials and Methods: We screened cohorts of infertile men to identify the cause of their infertility. Results: Our team has identified and caracterize...

Multipole-Bound Anions and Photodetachment Spectroscopy

Photoelectron spectra of MgO n n 1 5 reveal a surprising trend: The electron binding energy decreases from n 1 to 4, and then increases from 4 to 5. Ab initio calculations suggest this pattern is related to the electrostatic interaction between the extra electron and the charge distribution of the neutral cluster. This interaction is significant in MgO and MgO 2 5 , for which the lowest nonvani...
