Quenching of single-particle strength inferred from nucleon-removal transfer reactions on $^{15}$C / Jiang, Y.C. (SUSTech, Shenzhen ; Beijing, Inst. Atomic Energy) ; Chen, J. (SUSTech, Shenzhen ; Argonne) ; Kay, B.P. (Argonne) ; Hoffman, C.R. (Argonne) ; Tang, T.L. (Argonne) ; Tolstukhin, I.A. (Argonne) ; Xie, M.R. (Lanzhou, Inst. Modern Phys. ; UCAS, Beijing) ; Li, J.G. (Lanzhou, Inst. Modern Phys. ; UCAS, Beijing) ; Michel, N. (Lanzhou, Inst. Modern Phys. ; UCAS, Beijing) ; Avila, M.L. (Argonne) et al.
The difference in the proton and neutron separation energies ($ΔS$) of the weakly bound $^{15}$C ground state is -19.86 MeV, an extreme value. Data from intermediate-energy heavy-ion induced (HI-induced) knockout reactions on nuclei spanning $-20\lesssimΔS\lesssim+20$ MeV, suggest that the degree to which single-particle strength is quenched, $R\mathrm{_{s}}$, has a negative correlation with $ΔS$, decreasing from unity around $-20$~MeV to around 0.2 at $+20$~MeV.

Evolution of the nuclear spin-orbit splitting explored via the $^{32}$Si($d$,$p$)$^{33}$Si reaction using SOLARIS / Chen, J. (SUSTech, Shenzhen ; Argonne) ; Kay, B.P. (Argonne) ; Hoffman, C.R. (Argonne) ; Tang, T.L. (Argonne) ; Tolstukhin, I.A. (Argonne) ; Bazin, D. (Michigan State U.) ; Lubna, R.S. (Michigan State U.) ; Ayyad, Y. (Santiago de Compostela U., IGFAE) ; Beceiro-Novo, S. (Michigan State U.) ; Coombes, B.J. (Australian Natl. U., Canberra) et al.
The spin-orbit splitting between neutron 1$p$ orbitals at $^{33}$Si has been deduced using the single-neutron-adding ($d$,$p$) reaction in inverse kinematics with a beam of $^{32}$Si, a long-lived radioisotope. Reaction products were analyzed by the newly implemented SOLARIS spectrometer at the reaccelerated-beam facility at the National Superconducting Cyclotron Laboratory. [...]

Direct Determination of Fission-Barrier Heights Using Light-Ion Transfer in Inverse Kinematics / Bennett, S.A. (Manchester U.) ; Garrett, K. (Manchester U.) ; Sharp, D.K. (Manchester U.) ; Freeman, S.J. (Manchester U. ; CERN) ; Smith, A.G. (Manchester U.) ; Wright, T.J. (Manchester U.) ; Kay, B.P. (Argonne, PHY) ; Tang, T.L. (Argonne, PHY) ; Tolstukhin, I.A. (Argonne, PHY) ; Ayyad, Y. (Santiago de Compostela U., IGFAE) et al.
We demonstrate a new technique for obtaining fission data for nuclei away from $\beta$-stability. These types of data are pertinent to the astrophysical \textit{r-}process, crucial to a complete understanding of the origin of the heavy elements, and for developing a predictive model of fission. [...]

Probing the quadrupole transition strength of $^{15}$C via deuteron inelastic scattering / Chen, J. (Argonne) ; Kay, B.P. (Argonne) ; Tang, T.L. (Argonne) ; Tolstukhin, I.A. (Argonne) ; Hoffman, C.R. (Argonne) ; Li, H. (Lanzhou, Inst. Modern Phys.) ; Yin, P. (Lanzhou, Inst. Modern Phys.) ; Zhao, X. (Lanzhou, Inst. Modern Phys.) ; Maris, P. (Iowa State U.) ; Vary, J.P. (Ames Lab) et al.
Deuteron elastic scattering from 15C and inelastic scattering reactions to the first excited state of 15C were studied using a radioactive beam of 15C in inverse kinematics. The scattered deuterons were measured using HELIOS. [...]
