# Low-lying dipole strength in 52Cr

Description
The low-lying dipole strength in $^{52}$Cr was measured in nuclear　resonance fluorescence experiments using a quasi-monochromatic, linearly polarized photon beam. The parities of the excited dipole states were　determined by the intensity asymmetry of resonantly scattered $\gamma$-ray with respect to the polarization plane of the incident photon beam. We observed 62 resonances at excitation energies between 7.5 and 12.1 MeV. The observed $M1$ and $E1$ strengths were compared via random-phase approximation calculations using the Skyrme interaction. The effects of 2 particle-2 hole configuration mixing and tensor force on dipole strength distributions were investigated.
