Calculation ofB(E2)transition rates in1f72-shell nuclei with realistic effective interaction and charges

$B\left(E2\mathrm{}\right)\mathrm{}$ transition rates in $A=42\mathrm{}$ and $A=43\mathrm{}$ nuclei have been calculated in ${\mathrm{}\left(\mathrm{pf}\right)\mathrm{}}^n$ model spaces using an effective interaction and effective charges obtained by summing the diagrams of the Tamm-Dancoff approximation for screened particle-hole vertices. Good agreement with measured $B\left(E2\mathrm{}\right)\mathrm{}$ rates are obtained for transitions between high-spin states. The results are further very similar to those obtained by parametrizing the effective charges.
