Abstract
This paper concentrates on two topics. First it presents cases which show that even in atomic physics, contrary to expectations, variational methods have problems on the 4-5th digits in expectation values which depend on the values of Ψ at the cusps, as opposed to the energy. Second, we compare the results of the direct method, CFHHM (Correlation function hyperspherical harmonic method), in atomic ionization calculations of the single and double ionization of the Helium atom and the Helium isoelectronic sequence for Z up to 10 and excited states up to n = 5. We calculate more n, Z dependencies than before; make predictions on corrections due to quasi-free mechanism using a new formula (several new light sources are becoming available).
