Using the idea of equilibrium charge, we show that the electron capture of projectile leads to a screening energy which significantly exceeds the adiabatic limit in the simple consideration for the D(d,p)T reaction and provides a possibility to explain the large screening energy claimed in the analysis of experimental data. We then show that the Coulomb explosion can result in a large apparent screening energy as large as that encountered in the analysis of ^3He(d,p)^4He reactions induced by the molecular D_2^+ and D_3^+ projectiles at very low energies.11 pages, 1 figureNuclear Theorytext
