<p>photodissociation cross sections for the hydrogen molecular ion. v=0, ..., 18,N=0.</p> <p> </p> <p>Photodissociation cross sections for the hydrogen molecular were calculated using quantum-mechanical methods. The Born-Oppenheimer approximation is used (adiabatic, relativisitic, and non-adiabatic corrections are ignored) for (v,N) with v=0...18, and N=0.</p> <p>There are published tables with some of these values [1,2] with log plots for (v=0,N=1) and (v=9,N=1). The present values are in good agreement with those listed in [1].</p> <p> </p> <p>Refs.[3] and [4] give log plots for (0,0), (0,5), (0,8)</p> <p>and Ref. [3] gives a log plot for (7,0) and (7,8).</p> <p>Ref.[5] gives a linear plot for (10,0), (10,10), (10,15), and (10,20).</p> <...
