Abstract

A bremsstrahlung photon beam from electrons with end-point energies of 7.66 and 10.37 MeV was used for photoexciting levels in ²³Na. Values of gΓ²₀/Γ and gΓ₀ of 22 levels below 10 MeV were obtained using scattering and self-absorption measurements. The values for 7 levels are reported for the first time. The temperature variation of the scattering cross section was measured at T=300 K and T=78 K to study in some detail the effective temperature T_e of metallic ²³Na. The results of the total B(M1) strength of T=1/2 levels below 9 MeV were found to be in excellent agreement with the large-scale shell-model calculations.
