✦ Synopsis


In the problem of the "compressed helium atom", the boundary condition that the wave function ~0 must vanish at infinity (1" : oo), is replaced by : ~ = 0 at a finite r = r o. This problem is solved by a variational method, which for the limiting case of the free atom.(ro--+ oo) coincideswith one of H y 1 1 e r a a s' approaches tothe helium problem. The energy and kinetic energy of the electrons in the ground state are calculated as functions of r 0 and the corresponding pressure ( Β§ 5).

The helium atom, enclosed in a spherical box of radius r 0' has been used as a model of compressed helium. From wave functions for this model, the polarizability is calculated as a function of r 0 and the corresponding pressure. It is found that at 1000 atmospheres the polarizability is diminished b
