Further insights into the reaction ¹⁴Be(CH₂, X)¹⁰He

NUCLEAR REACTIONS ²H(¹⁴Be, ¹⁰He), (¹⁴Be, ¹²He), E=59 MeV/nucleon, [¹⁴Be secondary beam from ⁹Be(¹⁸O, X), E=120 MeV/nucleon primary reaction using A1900 fragment separator]; measured particle spectra by ΔE-E detectors and neutron spectra by MONA array at NSCL-MSU facility; analyzed decay energy spectra and multiplicity distributions for ⁸He+n, ⁸He+2n ⁸He+4n, and ⁸He+2n with α removal. ¹⁰He; deduced resonance, no evidence for initial state effects based on the halo structure of the initial ¹⁴Be assuming a direct α-particle removal reaction. ¹²He; deduced no evidence for the existence of a low-lying (≤1 MeV) resonance in ¹²He.
