Spontaneous Gamma Decay in the Case of Free Space

1 Spontaneous Gamma Decay in the Case of Free Space 

In the case of free space, we have oo and V p 0. At such a condition one can easily calculate the sum 

After mode (j3) averaging by the polarization state Cp in respect to d p, we have 

As follows from the common result (14.8), the small magnitude co in two last equations is equal to Aa o. With a high degree of precision in the expressions determining Fq and Acoq one can neglect the small magnitude of the field shift co.  

The sum Sg = —coa + co) that determines the influence of atom electrons subsystem on nuclear
