Theorie der Riesenresonanzen in sphärischen Kernen.

The dynamic collective theory has been developed for vibrational nuclei in a previous paper. Here the details are studied and compared with experiments. For this purpose the structure of the dipole operator has been established, the energy matrix of the dipole-quadrupole interaction has been diagonalized and the various approximations are discussed quantitatively in detail. It is interesting that this systematic theory gives the details of the γ-absorption cross section in many nuclei. [ABSTRACT FROM AUTHOR]
