Observation of α-t continuum states with relative energies of 0–2 MeV in7Li breakup reactions

Abstract The breakup of 7 Li at 63 MeV was studied in an α-t coincidence experiment using an Enge split pole spectrograph. For the first time, the entire spectrum of the α-t continuum states of 7 Li was observed in the range of the relative energy ɛ from zero to 2 MeV. A pronounced bump was found at ɛ ≈ 0.4MeV. The astrophysical implications of the data are discussed.
