Abstract

Excitation of H-** resonances in H-/rare gas collisions for energies from 2 to 7 keV has been studied. The resonances are observed using translational electron spectroscopy. In addition to well known Feshbach resonances lying below H(n = 2) and decaying to H(1s), we have identified Feshbach resonances lying below H(n = 3) decaying to H(n = 2) and H(1s). The resonance profiles exhibit strong interference patterns, depending on the target gas. Resonances below H(n = 4) have also been observed. Excitation of shape resonances lying above the H(n = 3) threshold is also suspected.
