Query: Comparison of delta- and Gogny-type pairing interactions   The matrix elements of the zero-range $\delta$-force and the finite range
Gogny-type pairing force are compared. The strengths of the
$\delta$-interaction for rare-earth nuclei are adjusted. Pairing gaps resulting
from different pairing interactions are compared to experimental ones.
