Title: Recent Direct Reaction Experimental Studies with Radioactive Tin Beams

Abstract

Direct reaction techniques are powerful tools to study the single-particle nature of nuclei. Performing direct reactions on short-lived nuclei requires radioactive ion beams produced either via fragmentation or the Isotope Separation OnLine (ISOL) method. Some of the most interesting regions to study with direct reactions are close to the magic numbers where changes in shell structure can be tracked. These changes can impact the final abundances of explosive nucleosynthesis. The structure of the chain of tin isotopes is strongly influenced by the Z = 50 proton shell closure, as well as the neutron shell closures lying in the neutron-rich, N = 82, and neutron-deficient, N = 50, regions. Here, we present two examples of direct reactions on exotic tin isotopes. The first uses a one-neutron transfer reaction and a low-energy reaccelerated ISOL beam to study states in Sn-131 from across the N = 82 shell closure. The second example utilizes a one-neutron knockout reaction on fragmentation beams of neutron-deficient Sn-^106,108Sn. In conclusion, In both cases, measurements of γ rays in coincidence with charged particles proved to be invaluable.

Direct neutron capture cross section on ${}^{80}{Ge}$ and probing shape coexistence in neutron-rich nuclei

Journal Article Ahn, S. ; Bardayan, D. W. ; Jones, K. L. ; ... - Physical Review C

Results are presented from the first neutron-transfer measurement on ⁸⁰Ge using an exotic beam from the Holifield Radioactive Ion Beam Facility at Oak Ridge National Laboratory. Newly measured spins and spectroscopic factors of low-lying states of ⁸¹Ge are determined, and the neutron capture cross section on ⁸⁰Ge was calculated in a direct-semidirect model to provide a more realistic (n,γ) reaction rate for r-process simulations. Furthermore, a region of shape coexistence around N ≈ 50 is confirmed and implications for the magic nature of ⁷⁸Ni are discussed.

Neutron transfer reactions on the ground state and isomeric state of a ¹³⁰Sn beam

Journal Article Grzywacz-Jones, Katherine ; Bey, A. ; Burcher, Sean ; ... - Physical Review. C

The structure of nuclei around the neutron-rich nucleus ¹³²Sn is of particular interest due to the vicinity of the Z = 50 and N = 82 shell closures and the r-process nucleosynthetic path. Four states in ¹³¹Sn with a strong single-particle-like component have previously been studied via the (d,p) reaction, with limited excitation energy resolution. Here, the ¹³⁰Sn(⁹Be,⁸Be)¹³¹Sn and ¹³⁰Sn(¹³C,¹²C)¹³¹Sn single-neutron transfer reactions were performed in inverse kinematics at the Holifield Radioactive Ion Beam Facility using particle-γ coincidence spectroscopy. The uncertainties in the energies of the single-particle-like states have been reduced by more than an order of magnitude using themore »« less

Constraining spectroscopic factors near the $r$ -process path using combined measurements: ${}^{86}{Kr}$ $(d,$ ${p)}^{87} Kr$

Journal Article Walter, D. ; Pain, S. D. ; Cizewski, J. A. ; ... - Physical Review C

Background: Current nuclear structure models indicate that the shell structure near the valley of stability, with well-established shell closures at N=50, for example, changes in very neutron-rich nuclei far from stability. Single-particle properties of nuclei away from stability can be probed in single-neutron (d,p) transfer reactions with beams of rare isotopes. The interpretation of these data requires reaction theories with various effective interactions. Often, approximations made to the final bound-state potential introduce a large uncertainty in the extracted single-particle properties, in particular the spectroscopic factor. Purpose: Mitigate this uncertainty using a combined measurement method to constrain the shape of the bound-state potential and to reliably extract the spectroscopic factor. Methods: The ²H(⁸⁶Kr,p)⁸⁷Kr reaction was measured at 33 MeV/u at the National Superconducting Cyclotron Laboratory (NSCL) as a test of the combined method. The reaction protons were detected with the Oak Ridge Rutgers University Barrel Array (ORRUBA) of position sensitive silicon strip detectors, the first implementation of ORRUBA coupled to the S800 spectrograph with fast beams at NSCL. Results: These measurements at 33 MeV/u are combined with previous studies of the ⁸⁶Kr(d,p) reaction at 5.5 MeV/u to demonstrate a successful case of the combined method to constrain the shape of the single-particle potential and deduce asymptotic normalization coefficients and spectroscopic factors. In particular, the single-particle asymptotic normalization coefficient for the ground state of ⁸⁷Kr was constrained to b_d5/2=6.46more »« less

Neutron-hole states in 131Sn and spin-orbit splitting in neutron-rich nuclei

Journal Article Orlandi, R. ; Pain, S. D. ; Ahn, S. ; ... - Physics Letters B

In atomic nuclei, the spin-orbit interaction originates from the coupling of the orbital motion of a nucleon with its intrinsic spin. Recent experimental and theoretical works have suggested a weakening of the spin-orbit interaction in neutron-rich nuclei far from stability. To study this phenomenon, we have investigated the spin-orbit energy splittings of single-hole and single-particle valence neutron orbits of ¹³²Sn. The spectroscopic strength of single-hole states in ¹³¹Sn was determined from the measured differential cross sections of the tritons from the neutron-removing ¹³²Sn(d, t)131Sn reaction, which was studied in inverse kinematics at the Holifield Radioactive Ion Beam Facility at Oakmore »« less
