报告摘要:

Electron atom/molecule resonances are temporary bound states in the continuum. We have developed and used some complex scaled multiconfigurational methods for the determination of resonance parameters for electron–atom and electron–molecule systems including open-shell initial and/or final states and highly correlated (nondynamical correlation) atoms and molecules. I present the theoretical background of complex scaling method to study electron–atom/molecule resonances. Then I discuss the complex scaled multiconfigurational self-consistent field method (CMCSCF) and the complex scaled multiconfigurational spin-tensor electron propagator method (CMCSTEP). In real space the multiconfigurational spin-tensor electronpropagator (MCSTEP) method gives very accurate and reliable ionization potentials and electron affinities. Similar good results for resonances are determined in complex space.
