Author

Vogel, O., Dewald, D., Brentano, P., Gableske, J., Krücken, R., Nicolay, N., Gelberg, A., Petkov, P., Gizon, A., Gizon, J., Bazzacco, D., Rossi Alvarez, C., Lunardi, S., Pavan, P., Napoli, D. R., Frauendorf, S., and Dönau, F.

Abstract

The four-quasiparticle magnetic dipole band in 128Ba has been investigated with the 96Zr(36S,4n)128Ba reaction at the GASP spectrometer of the Laboratori Nazionali di Legnaro. Linking transitions to the previously known positive parity states have been observed for the first time in this mass region and new transitions on top of the band have been found. The experimental results are compared to previously made tilted axis cranking calculations.

10. Detailed Angular Correlation Analysis with 4π Spectrometers: Spin Determinations and Multipolarity Mixing Measurements in 128Ba

Author

R., Frauendorf, S., Dönau, F., Janssens, R. V. F., and Carpenter, M. P.

Abstract

We analyze for the first time the full γγ directional correlations from oriented states (DCO) in an experiment performed with the GASP detector array. Our analysis based on a transformation of the directional information into expansion coefficients of an orthogonal basis. With this method, which we call SpeeDCO (spectral expansion of DCO), the complete DCO information is concentrated in 12 γγ coincidence spectra. The analysis is applicable to all detector arrays which uniformly cover the solid angle. We show that the complete DCO information can be used for a reliable and unique determination of spins and multipolarity mixing ratios in weakly populated bands. We were able to establish the spins and the positive parity of the Δ I=1 ''M1 band'' in 128Ba and multipolarity mixing ratios of M1/E2 in-band transitions were derived as well. The measured values are in good agreement with those expected for a high-K rotational band.

24. High spin states in 128Ba.

Author

Vogel, O., Chakrawarthy, R.S., Dewald, A., Petkov, P., Jessen, K., Gableske, J., von Brentano, P., Bazzacco, D., Gizon, A., Gizon, J., Lunardi, S., Napoli, D.R., Pavan, P., Rossi Alvarez, C., and Wiedenhöver, I.

Abstract

High spin states in 128Ba have been investigated with the fusion–evaporation reaction 96Zr(36S,4n)128Ba at a beam energy of 150 MeV with the GASP-spectrometer at INFN in Legnaro, Italy. The level scheme could be extended to higher spins and six-quasiparticle states have been observed. The deduced alignments are compared to the predictions of previously reported cranked shell model calculations. [ABSTRACT FROM AUTHOR]

25. Intruder bands in 113Sn.

Author

Chakrawarthy, R.S., von Brentano, P., Gableske, J., Dewald, A., Wirowski, R., Albers, S., and Schimmer, M.

Abstract

The level structure of 113Sn has been investigated. The data were obtained by in-beam γ-ray spectroscopy using the reaction 100Mo(18O,5n)113Sn at 70 MeV performed at the OSIRIS gamma array in the Institut für Kernphysik FN Tandem accelerator. We report in this short note the observation of two intruder type rotational bands in this nucleus. [ABSTRACT FROM AUTHOR]

26. Proton-neutron mixed-symmetry 3(+)(ms) state in 94Mo

Author

Pietralla N, Fransen C, von Brentano P, Dewald A, Fitzler A, Friessner C, and Gableske J

Abstract

We identify a Jpi = 3(+)(ms) state in 94Mo. This identification is based on six M1 and E2 strengths and is the first identification of a 3(+)(ms) state from B(M1) and B(E2) values. The transition strengths were determined from the measurement of Doppler shifts, branching ratios, and E2/M1 mixing ratios, obtained from gammagamma directional correlations following the 91Zr(alpha,n) reaction and the beta(+) decay of (94)Tc(m). The interacting boson model agrees with the observations, which prove the 2(+) mixed-symmetry states to be a building block in nuclear structure.
