Comment on "From Coulomb excitation cross sections to nonresonant astrophysical rates in three-body systems: The ¹⁷Ne case"

NUCLEAR REACTIONS ¹⁵O(2p, γ)¹⁷Ne, T=0.3-10 GK; calculated contribution to the reaction rate from 1/2+ states, and 1/2+ resonance. ²⁰⁸Pb(¹⁷Ne, X), E=500 MeV/nucleon; calculated Coulomb dissociation cross sections for the 1/2+ B(E1) distribution, for the total (1/2+ + 3/2+) B(E1) distribution, and from shifting of the 1/2+ resonance position. Comparison with experimental data. This comment is in response to critique by 2018Pa43 on the calculations in 2016Ca38 about the radiative capture for ¹⁷Ne formation.
