**expression**( 11 ) shows the sign and frequency dependence characteristic of a polarization charge resulting from the coupling to a collective mode with zero frequency . By using the**expression**of polarizability given in ...Page 246

1 > 0 Then , if in the zeroth - order approximation one assumes that the pair density is uniform in the nuclear space ,
