The vacuum ultraviolet emission of neon excited with a pulsed 100 MeV {sup 32}S{sup 9+} ion beam from the Munich Tandem van de Graaff accelerator was studied at pressures between 1.8 and 96.1 kPa. In the wavelength range between 70 and 110 nm the first, second, and third excimer continua were observed. From time- and pressure-dependent studies of the third continuum emission at a wavelength of 99 nm, rate coefficients {ital k}{sub 2}=(3.6{plus minus}0.3){times}10{sup {minus}13} cm{sup 3}/s for the bimolecular reaction Ne{sup 2+}+Ne{r arrow}2Ne{sup +} and {ital k}{sub 3}=(2.84{plus minus}0.09){times}10{sup {minus}31} cm{sup 6}/s for the termolecular reaction Ne{sup 2+}+2Ne{r arrow}(Ne{sup 2+}Ne){sup 2+}+Ne were determined.
