Application of regularized probability absorber states to He++H+ collisions

摘要: To improve on the behaviour of usual close coupling expansions at intermediate energies it has been recently proposed to enlarge basis with addition probability absorbers or doorway states. Application atomic requires regularization Coulomb potential interactions, either by using model potentials projection techniques. A preliminary application latter method benchmark He+(1s)+H+ collisional system is presented, a one-centre expansion, in range 10-500 KeV impact energies. Use different regularizations, together an analysis shape absorber functions, permits electron loss, ionization, charge exchange and excitation cross sections be obtained.
