Spectroscopy of ⁷He using the ⁹Be(⁶He, ⁸Be) transfer reaction

NUCLEAR REACTIONS ⁹Be(⁶He, ⁸Be)⁷He, E=16.8 MeV, [secondary ⁶He beam was produced in ⁷Li(p, 2p) by ISOL method]; measured particle spectra, time of flight, two-dimensional energy spectra of a1 and a2 in coincidence mode using annular single-sided silicon detector arrays at Cyclotron Research Center (CRC) in Louvain-la-Neuve; reconstructed relative energy of the two a particles, center-of-mass energy of 6He+n system. ⁷He; deduced excitation energy spectrum, levels, resonances, J, p, width, spectroscopic factors using R-matrix analysis. Comparison with previous experimental results. ⁹Be(⁶Li, ⁸Be)⁷Li E=17 MeV; measured a1 and a2 particle spectra, time of flight, two-dimensional energy spectra. ⁷Li; deduced excitation energy spectrum.
