Abstract: B29.00009 : Electronic stopping power of metallic clusters in TDDFT
1:15 PM–1:27 PM
For this purpose, we developed a real time TDDFT approach based on MOLGW code, a DFT and Green’s function Gaussian basis open source project . This implementation has several appealing advantages: the ability to incorporate core electrons, the ease of using the modern hybrid functionals, and the flexibility of the basis set.
We calculated the stopping power of protons in lithium clusters and evaluated their ability to represent the solid. A great care was taken about the basis set convergence and about the effect of the impact parameter. These results were successfully compared to our earlier linear response results for the solid  and to the SRIM reference.
