Energy levels in light nuclei
… model theory to the energy level structure of light nuclei has made apparent a lack of experimental data concerning these nuclei. The impossibility of accurately criticizing the theory on the basis of available experimental results has made imperative new investigations to determine the …

Energy levels in certain light nuclei
… with the object of studying energy levels of nuclei. Energy levels in excited C14 and N14 were studied by measuring the energy of the gamma rays emitted by these excited states. The excited levels were obtained by bombarding C13 with deuterons. Energy levels in Be8 and Be9 were studied by …

Doppler-Broadening of Light Nuclei Gamma-Ray Spectra
… are bombarded with neutrons which react with the nuclei of the atoms within causing a de-excitation process emitting a gamma-ray. The spectrum displayed by the collection of these gamma-rays gives valuable information regarding the material’s elemental make-up. It has been hypothesized that …

Helium-3 inelastic scattering from several light nuclei
9 Be, 12C, 24Mg , 25Mg , 26Mg , and 27Al targets were employed to scatter a 20.5 MeV 3He beam from the University of Illinois cyclotron. 3He energy spectra were obtained through the use of solid state detectors in a LiE-E telescope. Data were taken at laboratory angles of 15° to 115°, in 5° …

Two-nucleon short-range correlations in light nuclei
Understanding the nucleon-nucleon (NN) interaction is a fundamental task in nuclear physics, as NN-interaction models are a crucial input to modern nuclear structure calculations. While great progress has been made toward understanding this interaction, the available state-of-the-art models predict …

13 to 27 MeV helium-3 elastic scattering from several light nuclei
9Be , 1OB, 11B, 12c, 24Mg , 25Mg , 26Mg and 27Al targets have been bombarded with the 3He beam from the University of Illinois cyclotron. Elastic scattering angular distributions have been obtained in the approximate beam energy range of 13 to 27 MeV in steps of about 2 MeV and in the angular range …

Precise measurement of the nuclear dependence of structure functions in light nuclei
… effort has been to measure the effect in heavy nuclei where it has the same zBj dependence and differs only in magnitude. Calculations predict large differences in both the magnitude and zBj-dependence of the EMC effect in 3He and 4He and precise measurements of the EMC effect in these nuclei …

Energy dependence of the helium-3 induced charge exchange reaction on several light nuclei with n - z = 1
9Be , llB, 25Mg and 27Al targets have been bombarded with the He beam from the University of Illinois cyclotron. The angular distributions for the (3He ,t) charge exchange reaction have been obtained for 9Be at 20.2, 22.1, 24.9 and 27.8 MeV; for 11B at 20.2, 22.1, and 24.9 MeV; and for' 25 Mg and …

Applications of Nuclear Quadrupole Double Resonance Spectroscopy
… frequencies generally associated with the light nuclei (D, ('10)B, ('11)B, ('14)N, and ('17)O) and, in the case of ('17)O, the low natural abundance, the contribution of NQR spectroscopy to our understanding of chemical bonding has been small. Only recently have nuclear quadrupole double …

Pionless Effective Field Theory: Building the Bridge Between Lattice Quantum Chromodynamics and Nuclear Physics
… revealed to be an appropriate theory to describe light nuclei both in nature, and in the case where heavier quarks are used in order to make \ac{LQCD} calculation feasible. Our results are in good agreement with experiments and \ac{LQCD} predictions. In our \ac{LO} calculation, $^{16}$O appears to …

A Quantum Monte Carlo approach to dark matter-nuclei interaction
… scattering of dark matter (DM) particles off light nuclei, up to $A=6$ (d, $^3$H, $^3$He, $^4$He, and $^6$Li). DM-nucleon one- and two-body currents are obtained to next-to-leading order in chiral effective theory, and they are derived from a DM-quark and DM-gluon effective interaction. The …
