Efficient Basis Sets for Core-Excited States Motivated by Slater’s Rules

X-ray photoemission spectroscopy is a commonly applied characterization technique that probes the local chemistry of atoms in molecules and materials via the photoexcitation of electrons from atomic core orbitals. These...

Design and Development of Physics Learning Media of Three Dimensional Animation Using Blender Applications on Atomic Core Material

The Aims of this study is to design and build a three dimensional animated physics learning media on the atomic core material using blender application for High School Physics learning media for atomic core material is already exist but still in the form of two dimensions, so it less of visualize actual concept. This research used three-stage of development research. The first stage is the design stage of the media by using instructional design model type ADDIE. The second stage is the stage of media development using the blender application. The third stage is the stage of validation and reliability. Respondents amounted to 54 people consisting of 5 experts (Expert), 11 teachers (user experts), 20 teachers (users) and 18 students (users). Aspects assessed are pedagogic, content and technical. Data collection technique is questionnaire. The results showed the validity score of experts 4.515 which means the learning media is valid with very high category. The Cronbach alpha value of the teacher as user is 0.950 and from student as user is 0.889. it indicated that the media is reliable.

Effects of crystal structure and composition on the photocatalytic performance of Ta–O–N functional materials

In Ta–O–N functional materials, the interaction between atomic core and valence electronic states, and the overlapping between valence electronic states mainly influence the band gap and the band edge position. According to the requirements, Ta3N5 and TaON are suitable candidate materials for efficient photocatalyst.

DC field microscopy of Rydberg Li atoms

The DC field microscopy of Rydberg Li atoms has been studied on the basis of the semiclassical theory for the first time. In particular, we discuss the atomic core scattering effect in the ionization dynamics of the Rydberg Li atom. Unlike the case of the photoionization of a Rydberg H atom in an electric field, where the photoionization microscopy interference patterns are mainly caused by the Coulomb scattering and the electric field potential, for the photoionization of a Rydberg Li atom in an electric field, the influence of the atomic core scattering effect on the photoionization microscopy interference patterns plays an important role. In addition, the structure of the interference pattern, which contains the spatial component of the electronic wave function, evolves smoothly with the electron energy above the saddle point energy. The observed oscillatory patterns in the electron probability density distributions on the detector plane are interpreted within the framework of the semiclassical approximation, which can be considered as a manifestation of interference between various electron trajectories arriving at a given point from the atom to the detector plane. This study provides some reference values for future experimental research on photoionization microscopy of the non-hydrogen Rydberg atoms in the presence of external fields.
