| Abstract: | Collective excitations in the two-particle nucleus148Gd up to 2.9 MeV have been investigated by thepp′-reaction at 25 MeV beam energy, and angular distributions have been analyzed with standard DWBA calculations. It is found that148Gd has larger octupole- than quadrupole collectivity in the energy range investigated. The 3? strength distribution is in quantitative agreement with predicted results for the levels formed by the coupling of two valence particles to the146Gd core octupole phonon. |
