\begin{abstract}
The ground state energy of hydrogen and helium atom confined by a hard
prolate spheroidal cavity is calculated in the presence of plasma
environment. The effect of compression as well as the presence of plasma
environment on the energy of hydrogen and helium in ground state is
studied in details. The plasma effect is taken care of by employing
effective screening of the Coulomb potential. The Schrodinger equation
is solved using the variational Monte Carlo method with an accurate
trial wave function depending on many variational parameters. The
results were extended also to include He-like isoelectronic ions up to Z
= 10. Our results are compared with the most recent accurate values. The
obtained results are in good agreement with the most recent results.%
