In this contribution, the adequacy of the TFDA.W method for the study of many-electron atom confinement within different confinement conditions -by closed and open boundaries - is explored. We begin by making a brief review of the main strategy followed in the TFDA.W method to account for the study of many-electron atoms confined by hard and soft spherical boxes. Here, important quantitative corrections to our previous studies are introduced, leading to better agreement with other reference calculations,...

Two-electron systems are the most studied systems in quantum mechanics due to the fact that they are the simplest systems that contain the electron-electron interaction, which is a challenge for the solution of the Schrodinger equation [1], In particular, helium-like atoms are used many times as a reference to apply new theoretical and computational techniques. Additionally, in recent years the study of many-electron atoms confined spatially have a particular interest since the confinement induces important changes on the electronic structure of these systems [2, 3], The confinement imposed by rigid walls has been quite popular from the Michels proposal made 76 years ago [4], followed by Sommerfeld and Welker one year later [5]. Such a model assumes that the external potential has the expression...
