S.J. Mannanal,B. Boschung,M. Carlen,J.-Cl. Dousse,S. Drissi,P. E. Garrett,J. Kern,B. Perny,Ch. Rhême,J.P. Vorlet,C. Günthe,J. Manns,U. Müller +12 more
TL;DR: In this article, a level scheme consisting of 178 transitions among 6 well-developed and 4 partial rotational bands is proposed, and the results were interpreted in the framework of the Nilsson model by comparison with predictions.

Is there experimental evidence for an interpretation of the lowest K =0 collective excitation of deformed nuclei as a phonon excitation of the γ band?
TL;DR: It is concluded that there is no experimental evidence supporting the new interpretation of the {beta} vibrations in the deformed rare-earth nuclei.

TL;DR: In this paper, the (p, t) reaction was studied at 22 MeV proton energy using targets of 230,232Th and234,236,238U and the properties of the first two excited 0+ bands in228Th,232U and234U were compared and discussed.

TL;DR: In this paper, the branching ratios of the E2 transitions from the 01+, 21+, and 22+ bands are explained in the framework of the rotational model by taking into account the coupling of these bands with the ground-state band, and the coupling between the 01+ and 21+ bands.

Long-lived isomers in 190Ir
P. E. Garrett,P. E. Garrett,N. Warr,H. Baltzer,S. Boehmsdorff,D.G. Burke,M. Délèze,S. Drissi,J. Gröger,C. Günther,J. Kern,S.J. Mannanal,J. Manns,U. Müller,J.P. Vorlet,T. Weber +15 more
TL;DR: In this paper, a series of measurements, including excitation functions, half lives, e − γ coincidences and e − e − coincidences, was performed, and the results indicated that these transitions are fed by the 148.7 keV M4 transition that depopulates the 11 − isomer.
