Quantifying resonance behavior in the fusion of ¹⁷O with ¹²C at above-barrier energies

NUCLEAR REACTIONS ¹²C(¹⁷O, X)²⁹Si, E=47, 47.5, 48, 55 MeV; measured reaction products, evaporation residues, charged particles; deduced fusion excitation functions, fusion σ(E). Comparison to other experimental data including fusion data on ¹⁷F+¹²C system. Systematics of the fusion σ for ^16,17,18,19+¹²C systems. Gas filled (CH₄) active target MuSIC@Indiana at the University of Notre Dame Nuclear Science Laboratory.

Extracting model-independent nuclear level densities away from stability

RADIOACTIVITY ⁷⁶Ga(β^-); analyzed experimental total absorption spectrum (TAS) data in 2016Do05: Phys. Rev. C 93, 064317. ⁷⁶Ge; deduced γ-strength function (γSF), nuclear level density (NLD). Comparison to other experimental data and to γ-strength function in ⁷⁴Ge. ⁸⁸Br(β^-); measured Eγ, Iγ, TAS spectrum using Summing NaI (SuN) detector at Argonne CARIBU facility. ⁸⁸Kr; deduced γ-strength function (γSF), nuclear level density (NLD). Compared with other experimental data γ-strength functions for ⁸⁶Kr and ⁸⁷Kr. NLD results are compared to calculations done with 3 semi-microscopic models - HFB+Skyrme, HFB+Skyrme combinatorial, temperature-dependent HFB+Gogny. Combination of "shape" method with β-Oslo technique which allows extraction of NLD in model independent way.

NUCLEAR REACTIONS ⁸⁷Kr(n, γ), E<1 MeV; calculated σ(E) using newly obtained NLD. Values are given relative to calculated ones using current RIPL-3 recommended level densities.
