| Abstract: | The effect of high pressures on an atom is frequently simulated by enclosing the atom in an impenetrable spherical box. The spectrum of such a confined helium atom placed at the centre of a spherical box is investigated. A model potential is used to calculate the energies of twelve excited states and thereby the transition wavelengths for a range of values of the radius of the confining sphere. Applications of results are discussed. Received 29 August 2002 Published online 10 December 2002 RID="a" ID="a"e-mail: ypvsj@uottawa.ca |
