abstract = {<p style="text-align: justify;">A molecular beam experiment on the formation of $H^+_3$ has been carried
out by using tunable vacuum ultraviolet (VUV) synchrotron radiation. Reflectron
time-of-flight mass spectrometer is applied to detect the signal of $H^+_3.$ The ionization
energy (IE) of $H_2$ and the appearance energy (AE) of $H^+_3$ are determined to be
15.41 eV and 14.61 eV, respectively, by measurements of photoionization efficiency
(PIE) curves. Additionally, two most likely $H^+_3$ formation ways, $(H_2)2\rightarrow H^3_+ &nbsp;+H$ and $(H_2)_3 \rightarrow H^+_3 +H+H_2,$ are discussed by ab initio calculations at CCSD(T) and MP2 level
with aug-cc-pVQZ basis set and compared with the experimental result. The optimized
geometries of species involved in the dissociative photoionization channels are
also determined at MP2/aug-cc-pVQZ level.</p>},
