Photoexcitation of low-lying collective states in 156,158,160Gd
U.E.P. Berg,C. Bläsing,J. Drexler,R.D. Heil,U. Kneissel,W. Naatz,R. Ratzek,S. Schennach,R. Stock,T. Weber,H. Wickert,B. Fischer,H. Hollick,D. Kollewe +13 more
TL;DR: In this article, strong low-energy collective transitions in the deformed nuclei 156,158,160Gd were observed with nuclear resonance fluorescence techniques utilizing 3.5 MeV bremsstrahlung and a high-resolution Ge(Li) detector.
Journal ArticleDOI
Systematic study of low-lying dipole excitations in 156,158,160Gd by photon scattering
TL;DR: In this paper, high-resolution Ge-γ-detectors were used for nuclear resonance fluorescence experiments on deformed nuclei 156,158,160Gd using 4.1 MeV bremsstrahlung.
Journal ArticleDOI
Photoexcitation of dipole modes in 160,162,164Dy
C. Wesselborg,P. von Brentano,K. O. Zell,R.D. Heil,H.H. Pitz,U.E.P. Berg,U. Kneissl,S. Lindenstruth,U. Seemann,R. Stock +9 more
TL;DR: In this paper, high resolution photon scattering experiments on 160,162,164 Dy have revealed considerable fragmentation of dipole strength into two groups around 2.5 MeV and around 3 MeV.
Journal ArticleDOI
Observation of orbital magnetic dipole strength in the actinide nuclei 232Th and 238U
R.D. Heil,H.H. Pitz,U.E.P. Berg,U. Kneissl,K.-D. Hummel,G. Kilgus,D. Bohle,Achim Richter,C. Wesselborg,P. von Brentano +9 more
TL;DR: In this article, the authors reported the first observation of those J π = 1 + states in actinide nuclei that are excited by the M1 scissors mode, and the observed spreading of strength is again of the same magnitude that has been observed already in rare-earth nuclei.
Journal ArticleDOI
Distribution of orbital magnetic dipole strength in 156Gd
D. Bohle,Achim Richter,U.E.P. Berg,J. Drexler,R.D. Heil,U. Kneissl,H. Metzger,R. Stock,B. Fischer,H. Hollick,D. Kollewe +10 more
TL;DR: In this article, high resolution inelastic electron scattering and nuclear resonance fluorescence experiments on 156 Gd were combined to yield information on the distribution of orbital magnetic dipole strength.
