Title: $β$ -decay properties of the very neutron-rich isotopes ${}^{86}{Ge}$ and ${}^{86}{As}$

Abstract

For this research, the β -decay properties of very neutron rich nuclei ⁸⁶Ge and ⁸⁶As were measured at the Holifield Radioactive Ion Beam Facility at Oak Ridge National Laboratory. Spectroscopic information on new excited states in ⁸⁶As and in ⁸⁶Se was obtained and is interpreted within an advanced shell model approach. These calculations, previously explaining well the structure of ⁸⁴Ge and ⁸⁵Ge, are not able to reproduce all the experimentally determined features of the measured level schemes of ⁸⁶As and ⁸⁶Se. The Gamow-Teller decay of ⁸⁶Ge and ⁸⁶As is also investigated in a shell-model framework. The fission yield for ⁸⁶Ge is discussed.

Experimental study of $β$ and $β - n$ decay of the neutron-rich $N = 54$ isotone ${}^{87}{As}$

Journal Article Korgul, A. ; Rykaczewski, Krzysztof Piotr ; Grzywacz, R. ; ... - Physical Review. C, Nuclear Physics

The β-decay properties of neutron-rich ⁸⁷As produced in the proton-induced fission of ²³⁸U were studied at the Holifield Radioactive Ion Beam Facility at Oak Ridge National Laboratory. The low-energy excited states in N = 53 ⁸⁷Se and N = 52 ⁸⁶Se were identified through β - γ and β-delayed neutron-γ decay of ⁸⁷As , respectively. In conclusion, the experimental systematics of low-energy levels of N = 53 isotones, Z = 34 ⁸⁷Se, and Z = 32 ⁸⁵Ge, and along with an analysis of shell-model calculations, allow us to discuss the main features of excited states expected for the next Nmore » = 53 isotone, ⁸³Zn .« less

Reexamining Gamow-Teller decays near ${}^{78}{Ni}$

Journal Article Alshudifat, M. F. ; Grzywacz, Robert ; Madurga, M. ; ... - Physical Review C

Decays of neutron-rich nuclei ^82,83Zn and ^82,83Ga produced in proton-induced fission of ²³⁸U were studied at the Holifield Radioactive Ion Beam Facility using on-line mass separation and β–γ spectroscopy techniques. New γ-ray transitions were identified and level schemes, which include states at high excitation energies in the range between 3–7 MeV were constructed. These high-energy levels were identified to be populated through allowed Gamow-Teller β transitions, and their structure was interpreted with new shell-model calculations. Furthermore, a β-delayed neutron branching ratio of 69±7% was deduced for ⁸²Zn and revised β-decay half-life values of ⁸²Zn [155(17)(20) ms] and ⁸³Zn [122(28) ms]more » were determined.« less

Experimental study of the $β$ decay of the very neutron-rich nucleus ${}^{85}{Ge}$

The β -decay properties of the very neutron-rich nucleus ⁸⁵Ge, produced in the proton-induced fission of ²³⁸U, were studied at the Holifield Radioactive Ion Beam Facility at Oak Ridge National Laboratory. The level scheme of ₃₃⁸⁵As₅₂ populated in ⁸⁵Geβ γ decay was reconstructed and compared to shell-model calculations. The investigation of the systematics of low-energy levels in N =52 isotones together with shell-model analysis allowed us to provide an estimate of the low-energy structure of the more exotic N =52 isotone ⁸¹Cu.

Journal Article Korgul, A. ; Rykaczewski, Krzysztof Piotr ; Grzywacz, Robert Kazimierz ; ... - Physical Review C

In this study, the β-decay properties of the very neutron-rich ⁸⁴Ge nucleus were studied at the Holifield Radioactive Ion Beam Facility at Oak Ridge National Laboratory. Several new γ-transitions and levels were added to its decay scheme and the order of the two lowest-lying levels in the daughter ⁸⁴As was corrected. For the first time γ radiation following β-delayed neutron emission was observed. The shell-model calculations and apparent β transition intensities were used to guide the spin assignment to the ⁸⁴As levels, in particular for the low-energy part of the level scheme.

Evidence for Gamow-Teller Decay of ${}^{78}{Ni}$ Core from Beta-Delayed Neutron Emission Studies

Journal Article Madurga, M. ; Paulauskas, S. V. ; Grzywacz, R. ; ... - Physical Review Letters

The β-delayed neutron emission of ^83,84Ga isotopes was studied using the neutron time-of-flight technique. The measured neutron energy spectra showed emission from states at excitation energies high above the neutron separation energy and previously not observed in the β decay of midmass nuclei. The large decay strength deduced from the observed intense neutron emission is a signature of Gamow-Teller transformation. This observation was interpreted as evidence for allowed β decay to ⁷⁸Ni core-excited states in ^83,84Ge favored by shell effects. We developed shell model calculations in the proton fpg_9/2 and neutron extended fpg_9/2 + d_5/2 valence space using realistic interactionsmore »« less
