| Outline of Final Research Achievements |
In order to study catalytic reactions on metal clusters, we have developed a computationally less demanding and highly accurate method to estimate the reactivity and properties of such materials. Especially, we have invented the method to accurately calculate ionization energies, which is significantly important in estimating the reactivity and properties and experimentally observable. Conventionally, it has been believed that the second-order Green’s function method is qualitatively accurate but quantitatively insufficient. However, we showed that the method can derive considerably accurate ionization energy when the complete basis set limit is considered. According to this observation, we have developed the explicitly correlated second-order Green’s function method, which gives quantitatively correct ionization energy with smaller basis set.
