Can I read Production and Optical Constants of Ice Tholin from Charged Particle Irradiation of (1:6) C2H6/H2O at 77 K on EtoBox?

Production and Optical Constants of Ice Tholin from Charged Particle Irradiation of (1:6) C2H6/H2O at 77 K by B.N. Khare; W.R. Thompson; L. Cheng; C. Chyba; C. Sagan; E.T. Arakawa; C. Meisse; P.S. Tuminello is a Physics and Astronomy article available to read on EtoBox.

What is Production and Optical Constants of Ice Tholin from Charged Particle Irradiation of (1:6) C2H6/H2O at 77 K about?

Ices containing \(\mathrm{H}_{2} \mathrm{O}\) and small amounts of simple hydrocarbons, either in the form of clathrates or as intimate physical mixtures, are thought to be common outer Solar System condensates that were incorporated into comets and other bodies in the outer Solar System. We have previously shown that plasma irradiation of \(\mathrm{H}_{2} \mathrm{O}\) frost containing small quantities of \(\mathrm{CH}_{4}, \mathrm{C}_{2} \mathrm{H}_{6}, \mathrm{C}_{2} \mathrm{H}_{6}+\mathrm{NH}_{3}\), or \(\mathrm{C}_{2} \mathrm{H}_{2}\) produces complex organic residues (tholins), noted that residues from \(\mathrm{H}_{2} \mathrm{O} / \mathrm{CH}_{4}\) and \(\mathrm{H}_{2} \mathrm{O} / \mathrm{C}_{2} \mathrm{H}_{6}\) have very similar spectra (W. R. Thompson, B. G. J. P. T. Murray, B. N. Khare, and C. Sagan, 1987, J. Geophys. Res. 92, 14933-14947), and used these tholins to reproduce the 3.4- \(\mu \mathrm{m}\) spectra of cometary comae (C. Chyba and C. Sagan 1987, Nature 330, 350-353; C. F. Chyba, C. Sagan, and M. J. Mumma, 1989, Icarus 79, 362-381). Through 50 separate irradiations of (6:1) \(\mathrm{H}_{2} \mathrm{O} / \mathrm{C}_{2} \mathrm{H}_{6}\) ice over a 5 -month period
