Abstract
The modified smooth exterior scaling (MSES) method is applied for the first time to calculate the energy and the width of the electron-molecule scattering. The isoelectronic 2Π g N2 - and 2Π CO- shape resonances have been studied as a test case for the MSES method. The results obtained using this method are in good agreement with experimental results. The conventional smooth exterior scaling (SES) method with different paths has also been applied for comparison purposes.

Abstract
Interatomic Coulombic decay (ICD) is a radiationless decay mechanism occurring via electron emission in an inner-valence ionized weakly bound cluster. The ICD has been studied for the neon clusters Nen (n=2,...,5). The decay widths of the neon clusters are calculated using ab initio Green's function method. The non-Dyson version of Green's function is employed. This propagator is analytically continued into the complex energy plane with the aid of a complex absorbing potential, and the decaying states are found as resonance states in this plane.
