Resonant states in ⁷H: Experimental studies of the ²H(⁸He, ³He) reaction

NUCLEAR REACTIONS ²H(⁸He, ³He)⁷H, E=26 MeV/nucleon; ²H(¹⁰Be, ³He)⁹Li, [secondary ⁸He and ¹⁰Be beams from ⁹Be(¹¹B, X), E=33.4 MeV/nucleon, and ⁹Be(¹⁵N, X), E=49.7 MeV/nucleon, respectively, followed by fragment separation by ACCULINNA-2 fragment separator at the U-400M cyclotron of FLNR, JINR, Dubna]; measured recoil ³He particles, (³He)(³H)- and (³He)n-coin using two identical ΔE-E-E single-sided silicon-detector telescopes for ³He, a square array of 16 CsI(Tl) crystals for tritons from the decay of ⁷H, and a neutron spectrometer of 48 organic scintillator modules for the (¹⁰Be, ³He) reaction. ⁷H; deduced missing mass spectra, center-of-mass angular distributions, levels, resonances, J, π, widths. ⁹Li; deduced excitation spectrum. Comparison with previous experimental results. Angular distributions analyzed using DWBA/FRESCO calculations.
