Investigation of ¹¹B and ⁴⁰Ca levels at 8-9 MeV by nuclear resonance fluorescence

NUCLEAR REACTIONS ¹¹B, ⁴⁰Ca(polarized γ, γ'), E=8-9 MeV nearly monoenergetic and linearly polarized photon beams from the HIγS facility at TUNL; measured Eγ, Iγ, γ(θ, pol) using three HPGe detectors. ¹¹B, ⁴⁰Ca; deduced levels, J, π, polarization asymmetries, and branching ratios. ¹¹B; analyzed γ-ray multipolarity mixing ratios using (polarized γ, γ') data from the present experiment and those from 2009Ru04: Phys. Rev. C 79, 047601. Discussed relationship of different phase conventions in nuclear resonance fluorescence (NRF) experiments.
