Band Termination Spectroscopy in Er-157

S.J. Gale, J. Simpson, Mark A. Riley, John F. Sharpey-Schafer et autres

The level scheme of 157Er has been extended from a spin region where the nucleus behaves as a prolate rotor to a region where the spin is produced by the alignment of all or most of the available valence nucleons along the …

Band structures extending to very high spin in Xe126

Christian Rønn Hansen, G. Sletten, G.B. Hagemann, B. Herskind et autres

High-spin states in $^{126}\mathrm{Xe}$ have been populated in the $^{82}\mathrm{Se}$($^{48}\mathrm{Ca}$,4$n$)$^{126}\mathrm{Xe}$ reaction in two experiments, one at the VIVITRON accelerator in Strasbourg using the Euroball detector array, and a subsequent one with ATLAS at Argonne using the Gammasphere Ge-detector array. Levels and assignments …

Competition between collective and noncollective excitation modes at high spin in Ba 124

A. Al-Khatib, A. K. Singh, H. Hübel, P. Bringel et autres

High-spin states in $^{124}\mathrm{Ba}$ were investigated in two experiments using the $^{64}\mathrm{Ni}$($^{64}\mathrm{Ni}$, $4n$)$^{124}\mathrm{Ba}$ reaction at three different beam energies. In-beam \ensuremath{\gamma}-ray coincidences were measured with the Euroball and Gammasphere detector arrays. In the experiment with Euroball, the CsI detector array Diamant was …

Charged particle feeding of hyperdeformed nuclei in the A=118–126 region

B. Herskind, Gudrun B. Hagemann, G. Sletten, T. Døssing et autres

A breakthrough was recently obtained in the analysis of the so-called Hyper-Long-HyperDeformed (HLHD) experiment made at the EUROBALL-IV γ-detector array (EB). The 64 Ni + 64 Ni ⇒ 128 Ba* fusion reaction was studied at E beam = 255 and 261 MeV, …

First observation of excited states in Cs114 : Spectroscopy of the yrast ν(h11/2)⊗π(h11/2) band

John F. Smith, Angela M. Fletcher, Christopher J. Chiara, Michael P. Carpenter et autres

Excited states have been observed for the first time in the very neutron-deficient ${}_{55}^{114}{\mathrm{Cs}}_{59}$ nucleus. The assignment to $^{114}\mathrm{Cs}$ was made by detecting $\ensuremath{\gamma}$ rays in coincidence with evaporated charged particles and with recoiling evaporation residues. A rotational band has been observed …

Evidence for octupole correlations in Ba124,125

Paolo Mason, G. Benzoni, A. Bracco, F. Camera et autres

The $\ensuremath{\gamma}$ decay of the nuclei $^{124,125}\mathrm{Ba}$ has been investigated by means of the EUROBALL spectrometer, coupled to the DIAMANT array of charged-particle detectors, using the reaction $^{64}\mathrm{Ni}$ + $^{64}\mathrm{Ni}$ at ${E}_{\mathrm{beam}}=255$ and 261 MeV. In the nucleus $^{125}\mathrm{Ba}$ six new E1 …

Structural behavior of Dy157,158,159 in the I=30−50ℏ spin regime

A. Pipidis, Mark A. Riley, J. Simpson, R. V. F. Janssens et autres

Significant extensions to the high-spin excitation spectrum of the $N=91$, 92, 93 isotopes $^{157,158,159}\mathrm{Dy}$ have been achieved using the high-efficiency \ensuremath{\gamma}-ray spectrometers Euroball and Gammasphere. These nuclei were populated via weak 3n or $\ensuremath{\alpha}\mathrm{xn}$ exit channels in fusion evaporation reactions. In $^{157}\mathrm{Dy}$, …

High-spin states in 124Ba were populated using the 64Ni(64Ni,4n)124Ba reaction at beam energies of 255 and 261 MeV. Gamma-ray coincidences were measured using the EUROBALL detector array.The charged-particle detector array DIAMANT provided channel selection. The previously known rotational bands are extended to …
