Charge-State Distributions After Radiative Capture

We present new measurements of the charge-state distributions (CSD) of a 1.068 MeV/u C beam in He, and of the 6+ : 5+ charge-state population ratio in the recoils of the ¹²C(α,ϒ)¹⁶O reaction, noth measured at the DRAGON recoil mass spectrometer. A computer simulation to model the CSD of both beam and recoil particles in inverse-kinematics experiments is compared to data from this work and from previous work at ERNA. The simulation provides good agreement with both data sets. The results suggest that, for this fusion reaction on the J^π=4+ resonance at E_beam=1.064 MeV/u, immediately after fusion, the recoil ions contain only the nucleons and not the electrons of the target He atom.
