Chaos and regularity in the spectra of the low-lying dipole excitations of 50, 52, 54Cr

NUCLEAR STRUCTURE 50,52,54Cr; analyzed experimental B(M1) strengths for 1+ states from orbital magnetic-dipole scissors mode, and sizable spin-flip magnetic-dipole strength, and experimental B(E1) strengths for 1- states belonging to the pygmy dipole resonances (PDRs) through random matrix theory (RMT) to analyze fluctuation properties in the subspectra of the energy levels; deduced Gaussian orthogonal ensemble (GOE) for 1+ states, and nearly Poissonian behavior for the 1- states, suggesting collective behavior of the PDRs. Relevance to nuclear resonance fluorescence experiments at the Superconducting Darmstadt Electron Linear Accelerator (S-DALINAC), and the high intensity γ-ray source (HIγS) of the Triangle Universities Nuclear Laboratory (TUNL).
