Strong evidence for 9N and the limits of existence of atomic nuclei

R. J. Charity, J. Wylie, S. M. Wang +21

The boundaries of the Chart of Nuclides contain exotic isotopes that possess extreme proton-toneutron asymmetries. Here we report on strong evidence of 9N, one of the most exotic p…

Uncertainty-quantified phenomenological optical potentials for single-nucleon scattering

C. D. Pruitt, J. E. Escher, R. Rahman

Optical-model potentials (OMPs) continue to play a key role in nuclear reaction calculations. However, the uncertainty of phenomenological OMPs in widespread use -- inherent to any…

Optical potentials for the rare-isotope beam era

C. Hebborn, F. M. Nunes, G. Potel +26

We review recent progress and motivate the need for further developments in nuclear optical potentials that are widely used in the theoretical analysis of nucleon elastic scatterin…

Using spin alignment of inelastically-excited fast beams to make spin assignments: the spectroscopy of 13O as a test case

R. J. Charity, T. B. Webb, J. M. Elson +23

Excited states in 13O were investigated using inelastic scattering of an E/A=69.5-MeV 13O beam off of a 9Be target. The excited states were identified in the invariant-mass spectra…

Almost medium-free measurement of the Hoyle state direct-decay component with a TPC

J. Bishop, G. V. Rogachev, S. Ahn +14

Background: The structure of the Hoyle state, a highly -clustered state at 7.65 MeV in , has long been the subject of debate. Understanding if the system compri…

Evidence against the Efimov effect in from spectroscopy and astrophysics

J. Bishop, G. V. Rogachev, S. Ahn +16

Background: The Efimov effect is a universal phenomenon in physics whereby three-body systems are stabilized via the interaction of an unbound two-body sub-systems. A hypothetical…

Isotopically resolved neutron total cross sections at intermediate energies

C. D. Pruitt, R. J. Charity, L. G. Sobotka +9

The neutron total cross sections of O, Ni, Rh, and Sn have been measured at the Los Alamos Neutron Science Center (LANSCE) from lo…

Systematic Matter and Binding-Energy Distributions from a Dispersive Optical Model Analysis

C. D. Pruitt, R. J. Charity, L. G. Sobotka +2

We present the first systematic nonlocal dispersive optical model analysis using both bound-state and scattering data of O, Ca, Ni, Sn, an…

A dispersive optical model analysis of Pb generating a neutron-skin prediction beyond the mean field

M. C. Atkinson, M. H. Mahzoon, M. A. Keim +4

A nonlocal dispersive-optical-model analysis has been carried out for neutrons and protons in Pb. Elastic-scattering angular distributions, total and reaction cross section…

Particle decays of levels in N and O investigated with the invariant-mass method

T. B. Webb, R. J. Charity, J. M. Elson +23

Particle-decaying states of the light nuclei N and O were studied using the invariant-mass method. The decay energies and intrinsic widths of a number of states we…

On Determining Dead Layer and Detector Thicknesses for a Position-Sensitive Silicon Detector

J. Manfredi, Jenny Lee, W. G. Lynch +19

In this work, two particular properties of the position-sensitive, thick silicon detectors (known as the "E" detectors) in the High Resolution Array (HiRA) are investigated: the th…
