    "abstract": "The influence of the size and shape of a dispersing and absorbing dielectric\nbody on the local-field corrected spontaneous-decay of an excited atom embedded\nin the body is studied on the basis of the real-cavity model. By means of a\nBorn expansion of the Green tensor of the system it is shown that to linear\norder in the susceptibility of the body the decay rate exactly follows Tomas\u0027s\nformula found for the special case of an atom at the center of a homogeneous\ndielectric sphere [Phys. Rev. A 63, 053811 (2001)]. It is further shown that\nfor an atom situated at the interior of an arbitrary dielectric body this\nformula remains valid beyond the linear order. The case of an atom embedded in\na weakly polarizable sphere is discussed in detail.",
