NUCLEAR REACTIONS ²⁶Mg(¹⁴C, np)³⁸Cl, E=30, 37 MeV; measured Eγ, Iγ, Ep, Ip, γγ- and pγ-coin, γγ(θ)(DCO), γ-polarization asymmetry using enriched target, FSU array of three Clover HPGe detectors and three single-crystal Ge detectors for γ detection, and ΔE-E telescope for particles at FSU Tandem accelerator. ³⁸Cl; deduced levels, J, π, multipolarities, configurations. Comparison with shell-model calculations using the FSU effective interaction for the spsdfp space.²⁴Mg, ³⁸Ar; deduced polarization asymmetries and multipolarities for two γ rays in each nucleus.
