Title: Single-particle shell strengths near the doubly magic nucleus 56Ni and the 56Ni(p,γ)57Cu reaction rate in explosive astrophysical burning

Abstract

Angle-integrated cross-section measurements of the ⁵⁶Ni(d,n) and (d,p) stripping reactions have been performed to determine the single-particle strengths of low-lying excited states in the mirror nuclei pair ⁵⁷Cu-⁵⁷Ni situated adjacent to the doubly magic nucleus ⁵⁶Ni. The reactions were studied in inverse kinematics utilizing a beam of radioactive ⁵⁶Ni ions in conjunction with the GRETINA γ-array. Spectroscopic factors are compared with new shell-model calculations using a full pƒ model space with the GPFX1A Hamiltonian for the isospin-conserving strong interaction plus Coulomb and chargedependent Hamiltonians. These results were used to set new constraints on the ⁵⁶Ni(p,γ)⁵⁷Cu reaction rate for explosive burning conditions in x-ray bursts, where ⁵⁶Ni represents a key waiting point in the astrophysical rp-process.

Determining the $r p$ -Process Flow through ${}^{56}{Ni}$ : Resonances in ${}^{57}{Cu} (p, γ) {}^{58}{Zn}$ Identified with GRETINA

Journal Article Langer, C. ; Montes, F. ; Aprahamian, A. ; ... - Physical Review Letters

An approach is presented in this paper to experimentally constrain previously unreachable (p,γ) reaction rates on nuclei far from stability in the astrophysical rp process. Energies of all critical resonances in the ⁵⁷Cu(p,γ)⁵⁸Zn reaction are deduced by populating states in ⁵⁸Zn with a (d,n) reaction in inverse kinematics at 75 MeV/u, and detecting γ-ray-recoil coincidences with the state-of-the-art γ-ray tracking array GRETINA and the S800 spectrograph at the National Superconducting Cyclotron Laboratory. The results reduce the uncertainty in the ⁵⁷Cu(p,γ) reaction rate by several orders of magnitude. Finally, the effective lifetime of ⁵⁶Ni, an important waiting point in the rpmore »« less

We report the mass measurement of ⁵⁶Cu, using the LEBIT 9.4 T Penning trap mass spectrometer at the National Superconducting Cyclotron Laboratory at Michigan State University. The mass of ⁵⁶Cu is critical for constraining the reaction rates of the ⁵⁵Ni(p,y), ⁵⁶Cu(p,y), ⁵⁷Zn(β⁺) ⁵⁷Cu bypass around the ⁵⁶Ni waiting point. Previous recommended mass excess values have disagreed by several hundred keV. Our new value, ME = -38626.7(7.1) keV, is a factor of 30 more precise than the extrapolated value suggested in the 2012 atomic mass evaluation [Chin. Phys.

Rotational Bands in the Doubly Magic Nucleus N{number_sign}⁵⁶ⁱ

Journal Article Rudolph, D ; Baktash, C ; Brinkman, M J ; ... - Physical Review Letters

Structures of the medium- to high-spin states in the doubly magic nucleus {sup 56}Ni have been investigated using the reaction {sup 28}Si({sup 36}Ar,thinsp2{alpha}) and the {gamma} -ray spectrometer Gammasphere in conjunction with the 4{pi} charged-particle detector array Microball. Two well-deformed rotational bands have been identified. There is evidence that one of the bands, which is identical to a sequence in the odd-odd neighbor {sup 58}Cu , partially decays via proton emission into the ground state of {sup 55}Co . Predictions of extensive large-scale shell-model and cranked Hartree-Fock and Hartree-Fock-Bogolyubov calculations are compared with the experimental data. {copyright} {ital 1999} {italmore » The American Physical Society}« less
