Abstract  The static electric dipole polarizabilities of the ground state and n ≤ 3 excited states of lithium atom embedded in a weekly coupled plasma environment are investigated as a function of the plasma screening radium. The plasma screening of the Coulomb interaction is described by the Debye-Hückel potential and the interaction between the valence electron and the atomic core is described by a model potential. The electron energies and wave functions for both the bound and continuum states are calculated by solving the Schrödinger equation numerically using the symplectic integrator. The oscillator strengths, partial-wave, and total static dipole polarizabilities of the ground state and n ≤ 3 excited states of lithium atom are calculated. Comparison of present results with those of other authors, when available, is made. The results for the 2s ground state demonstrated that the oscillator strengths and the static dipole polatizabilities from np orbitals do not always increase or decrease with the plasma screening effect increasing, not like that for hydrogen-like ions, especially for 2s → 3p transition there is a zero value for both the oscillator strength and the static dipole polatizability for screening length D=10.3106a0, which is associated with the Cooper minima.
