The wave function of light deuteron-like particles in the field of heavy nuclei has been solved recently by considering a charged particle ("proton") with mass m_p and charge Z_p and a neutral particle ("neutron") with mass m_n in the presence of target charge Z_T [1]. From these expressions the internal wave function of a light deuteron-like particle in the Coulomb field of heavy nucleus is derived in an approximate analytical form. It is shown, that in the Coulomb field of a heavy nucleus, the internal stationary state of a light deuteron-like particle can be transformed into a quasi-stationary one in which the particle may either polarize or break up into parts. Since the field of the target nucleus leeds to a significant distortion of the internal wave functions, their spherical symmetry becomes broken as the particle with approach the target. In this contribution we present the wave function calculations for d, ⁶He, ¹¹Li ions in the Coulomb field of ²⁰⁸Pb nuclei.
