Aspects of the influence of a strong Debye plasma environment on the negative hydrogen ion and the neutral helium atom have been studied. Contrary to earlier work, in the present calculation all interactions have been screened. This increases the stability of the systems to the extent that neither the H ‐ ion nor the ground state of helium will lose an electron by pressure ionization. It has been found that the charge distribution of H ‐ remains remarkably constant over a vast range of values of the Debye parameter D . © 1996 John Wiley & Sons, Inc.
