The ground state of the helium atom in a semi‐infinite space limited by a paraboloidal boundary, with the nucleus at the focus, is evaluated variationally. The pressure and electric dipole moment of the semiconfined atom are evaluated as functions of the position of the boundary. Estimates of the boundary positions and pressure variations at the successive ionization thresholds are established. © 1997 John Wiley & Sons, Inc. Int J Quant Chem 65 : 269–275, 1997
