Abstract

The experimental study of the helium decays of the 10Be and 12Be excited states was performed at TRIUMF, Vancouver, using the transfer reactions of the 9Li beam on the LiF target and resonant particle spectroscopy technique. Part of the results from the full dataset are presented here, for the 4He+6He (0+; 1.8 MeV, 2+), 6He+6He (0+; 1.8 MeV, 2+), and 4He+8He decays of the 10Be and 12Be excited states, respectively. The 6He+6He (1.8 MeV, 2+) decay channel was observed for the first time in the present experiment, while for the 4He+6He (1.8 MeV, 2+) decay channel, there was previously only one measurement available, which present results agree with. New highly excited states were observed in all decay channels studied. Although branching ratios and the spins of the states were not determined, important spectroscopic information is obtained and present results are in good agreement with the proposed α–Xn–α molecular structure of these isotopes, based on the comparison with previously published results.
