English We give a detailed account on our semiempirical calculations of the forbidden electric tensor polarizability α₂⁽³⁾ of the ground state of free Cs atoms and of Cs atoms implanted in a solid 4He matrix. The results are compared with measurements of α₂⁽³⁾ in the free atoms [Europhys. Lett. 76, 1074 (2006)] and in He-trapped atoms [Phys. Rev. A 75, 042505 (2007)]. Features with respect to calculations by other authors are the inclusion of off-diagonal hyperfine interactions and an analysis of contributions from continuum states, which turn out to be negligible. For both samples the results of the calculations are in good agreement with the experimental values, thereby settling a long-standing discrepancy.
