The mutable nature of particle-core excitations with spin in the one-valence-proton nucleus 133Sb
G. Bocchi, S. Leoni, B. Fornal +43
The gamma-ray decay of excited states of the one-valence-proton nucleus 133Sb has been studied using cold-neutron induced fission of 235U and 241Pu targets, during the EXILL campai…
Nuclear structure of Ac-231
R. Boutami, M. J. G. Borge, H. Mach +10
The low-energy structure of 231Ac has been investigated by means of gamma ray spectroscopy following the beta-decay of 231Ra. Multipolarities of 28 transitions have been establishe…
Total Routhian surface calculations for neutron-rich 149Ce
R. Kaczarowski, W. Plociennik, A. Syntfeld +4
Total Routhian Surface (TRS) calculations were performed for the 149Ce nucleus. The equilibrium deformation parameters and total angular momentum values have been calculated as a f…
On the difference between proton and neutron spin-orbit splittings in nuclei
V. I. Isakov, K. I. Erokhina, H. Mach +2
The latest experimental data on nuclei at Sn permit us for the first time to determine the spin-orbit splittings of neutrons and protons in identical orbits in this neutron…
Enhanced time response of 1-in. LaBr3(Ce) crystals by leading edge and constant fraction techniques
V. Vedia, H. Mach, L. M. Fraile +2
We have characterized in depth the time response of three detectors equipped with cylindrical LaBr (Ce) crystals with dimensions of 1-in. in height and 1-in. in diameter, and…
Beta-decay of Mn-65 to Fe-65
B. Olaizola, L. M. Fraile, H. Mach +13
The low energy structure of Fe-65 has been studied by means of gamma- and fast-timing spectroscopy. A level scheme of Fe-65 populated following the beta-decay of Mn-65 was establis…
Identification of the slow E3 transition 136mCs -> 136Cs with conversion electrons
K. Wimmer, U. Koester, P. Hoff +11
We performed at ISOLDE the spectroscopy of the decay of the 8- isomer in 136Cs by and conversion-electron detection. For the first time the excitation energy of the isomer and the…
Fast-timing study of Ga from the decay of Zn
V. Paziy, L. M. Fraile, H. Mach +23
The $β^{-}$ decay of Zn to the neutron magic nucleus Ga, with only three valence protons with respect to Ni, was investigated. The study was performed…
On the isospin dependence of the mean spin-orbit field in nuclei
V. I. Isakov, K. I. Erokhina, H. Mach +2
By the use of the latest experimental data on the spectra of Sb and Sn and on the analysis of properties of other odd nuclei adjacent to doubly magic closed shells…
Shape coexistence near the neutron number N=20: First identification of the E0 decay from the deformed 0^+_2 state in 30Mg
W. Schwerdtfeger, P. G. Thirolf, K. Wimmer +17
The 1789 keV level in 30Mg was identified as the first excited 0^+ state by measuring its E0 transition to the ground state. The measured small value of rho^2(E0,0^+_2 --> 0^+_1) =…
Detailed spectroscopy of doubly magic Sn
J. Benito, L. M. Fraile, A. Korgul +85
The structure of the doubly magic Sn has been investigated at the ISOLDE facility at CERN, populated both by the $β^-$decay of In and $β^-$-delayed ne…
Search for octupole correlations in Nd
E. Ruchowska, H. Mach, M. Kowal +3
Properties of excited states in Nd have been studied with multispectra and coincidence measurements. Twenty-four new -lines and three new levels have been introd…
