<p>gallium arsenide, GaAs, has gained widespread use in semiconductor devices that convert light and electrical signals in fiberoptic comunications systems. Gallium consists of 60.% Ga69 and 40% Ga71. Arsenic has only1 naturally occurring isotope, As75. Gallium arsenide is a polymeric material, but its mass spectrum shows fragments with formulas GaAs and Ga2As2. what would the distribution of peaks look like for these two fragments?</p>
