摘要：

The vacuum energy of a scalar field in a spherically symmetric background field is considered. It is expressed through the Jest function of the corresponding scattering problem. The renormalization is discussed in detail and performed using the uniform asymptotic expansion of the Jest function. The method is demonstrated in a simple explicit example.
