Nuclear energy level complexity: Fano factor signature of chaotic behavior of nearest-neighbor time-series analysis

NUCLEAR STRUCTURE ⁴⁸Ca, ^46,48Ti; calculated eigenvalue sequence as function of the number of 3+ states for different quadrupole strengths, Wigner distribution and Fourier power spectrum of the energy level spacings, Fano factor as function of the quadrupole intensity, and this factor corresponding to the quantum chaos for the energy levels in the nuclear spectra.

Importance of resonance widths in low-energy scattering of weakly bound light-mass nuclei

NUCLEAR STRUCTURE ⁹Be; calculated levels, resonances J, π, widths of a compound nucleus with ⁸Be+n cluster by solving the Lippmann-Schwinger equations in momentum space. Comparison with multichannel algebraic scattering (MCAS) calculations with target states.

NUCLEAR REACTIONS ⁸Be(n, n), E<5.5 MeV; ¹²C(n, n), (n, X), E<6.5 MeV; calculated elastic and reaction σ(E) coupled to first 0+, 2+ and 4+ states in ⁸Be, reaction σ with particle emission widths of ¹²C coupled to g.s., first 2+ and first excited 0+ states in ¹²C; deduced effect of particle-emitting resonances on the scattering cross section. Method involved choosing an appropriate target-state resonance shape, modifying a Lorentzian by use of widths dependent on projectile energy, with a correction to target-state centroid energy.
