Effects of Anion Excited States on Photodetachment of Negative Ions
… is observed for diatomic (AgF<super>-</super>, CuF<super>-</super>) and triatomic (NiO<sub>2</sub><super>-</super>, CuOF<super>-</super>) anions. The mechanism of the autodetachment (vibrational or electronic autodetachment) is explored using ab initio calculation. EOM-CCSD calculation reveals a …

Develpoment of advanced structural multifield models for the study of smart wing
… of this work. The Carrera Unified Formulations (CUF) give the possibility to run various theories for an assigned problem (materials, geometry, lamination lay-out, boundary conditions) at the same time. Trough the use of the CUF it is possible to introduce the so-called mixed axiomatic/asymptotic …
