A. Young and C. M. Surko<br/>Measurements of positron-on-molecule annihilation have established that positrons attach to a variety of molecules via vibrational Feshbach resonances (VFRs). These resonances, in turn, result in greatly enhanced positron annihilation rates beyond those expected in simple collisions. A recent paper ...<br/>[Phys. Rev.

When the velocity is about 3v_{Bohr} , the values of R_{21} by C^{q+} reach a maximum and are found to be 2 times the values for bare ions such as He^{2+} and Li^{3+} . A simple model is presented to estimate the single and double ionization cross sections of helium by various ions, and to present the scenario of multi-ionization in the low to intermediate energy range.
