"... In PAGE 3: ...The excimer wavelength of 248 nm is commonly used because it is strongly absorbed by most materials. The radiation and optical parameters of the excimer laser are presented in Table1 . From this table we see that this laser has a pulse energy density of 150 mJ/cm2 at a maximal repetition rate of 200 Hz.... ..."

"... In PAGE 7: ...4 Habing (1968) estimated the intensity of interstellar starlight at = 1000 A to be u = 4 10?14 erg cm?3. We will consider various radiation elds u , and will characterize the intensity of each at 1000 A, relative to Habing apos;s estimate, by the dimensionless factor [ u ]1000 A 4 10?14 erg cm?3 : (20) In Table1 we list spectral forms which have been considered by various workers. For each spectrum we list the photon ux in the 1110 ? 912 A interval, F 1110 A Z 912 A h?1 u d ; (21) the logarithmic derivative d ln u =d ln evaluated at 1000 A, and the color temperature Tcolor, the temperature of a blackbody having the same logarithmic derivative at 1000 A.... In PAGE 8: ... This radiation eld was employed by van Dishoeck amp; Black (1986) in their modelling of di use clouds, and by Black amp; van Dishoeck (1987) in their models of photodissociation fronts. As seen in Table1 , this spectrum is somewhat harder than eq. (23).... In PAGE 8: ...5 Pumping rates and dissociation rates for optically-thin H2 in various rotation-vibration states are given in Table 2 for the radiation elds (24) and (23). Also given in Table1 is the probability pdiss(v; J) that photoexcitation out of level X(v; J) will be followed by dissociation, and the probability hpret(v; J)i that photoexcitation out of X(v; J) will be followed by direct spontaneous decay back to the original level X(v; J). Since there are many possible UV transitions possible out of any given level X(v; J), both pdiss and hpreti depend on the shape of the illuminating spectrum, but Table 2 shows that for unshielded H2 the changes in hpdissi or pret are typically only a few percent when the shape of the radiation eld is changed.... In PAGE 41: ... Their models had IUV = 300 which (cf. Table1 ) corresponds to 670 { a factor of 7.5 weaker than the = 5000 favored here.... ..."

"... In PAGE 3: ... The optical sub-assembly is then mounted in a hermetically sealed, ceramic 8-pin Dual In-Line (DIL) package. Table1 outlines the number of devices irradiated and the fluence/dose received by each device. p-i-n silicon submount fibre... In PAGE 4: ... The average energy of the neutrons was 6MeV. The neutron fluence was measured by activated foil dosimetry (using 4mm diameter Ni foils) with the different fluences given in Table1 . The absolute accuracy is ~15% due to a systematic uncertainty in the activation cross-sections, but fluence measurements are typically reproducible to within a few percent.... ..."
