| dc.description | The Casimir energy of a solid ball placed in an infinite medium is calculated by a direct frequency summation using the contour integration. It is assumed that the permittivity and permeability of the ball and medium satisfy the condition $ε_1 μ_1=ε_2μ_2$. Upon deriving the general expression for the Casimir energy, a dilute compact ball is considered $(ε_1 -ε_2)^2/(ε_1+ε_2)^2\ll 1$. In this case the calculations are carried out which are of the first order in $ξ^2$ and take account of the five terms in the Debye expansion of the Bessel functions involved. The implication of the obtained results to the attempts of explaining the sonoluminescence via the Casimir effect is shortly discussed. | |
