Invariant-mass spectroscopy of ¹⁰B, ¹¹C, ¹⁴F, ¹⁶F, and ¹⁸Na

NUCLEAR REACTIONS ⁹Be(¹⁵O, X)¹⁶F/¹⁸Na/¹¹C/¹⁰B, E=48.1 MeV/nucleon; ⁹Be(¹⁷Ne, X)¹⁶F/¹⁸Na/¹¹C/¹⁰B, E=48.1 MeV/nucleon; measured charged particle spectra, angular distributions, Eγ, Iγ, γ(θ), (particle)γ-coin; deduced invariant mass-spectrum. ⁹Be(¹³O, X)¹⁴F/¹¹C/¹⁰B, E=69.5 MeV/nucleon; measured charged particles, (particle)(particle)-coin; deduced invariant mass-spectrum. ^16,14F, ¹⁸Na; deduced levels, J, π, S(p), proton-decay widths, nγ-decay widths, d-wave resonances spectroscopic factors. ¹⁰B; deduced levels, J, π, 4⁺ state - member of T=1 rotational band. ¹¹C; deduced levels, J, π from analysis of invariant-mass spectrum of 2α+³He and ⁶Li+α+p events. Comparison to previous experimental data and shell-model calculations. Systematics of analog rotational bands in ¹⁰C, ¹⁰B and ¹⁰Be. High-resolution array (HiRA) consisting of 14 Si-CsI(Tl) at NSCL (MSU). For the experiments with ¹⁵O and ¹⁷Ne beams setup was extended by CAESAR (CAESium iodide ARray) consisted of 158 CsI(Na) crystals.
