Hiby, Julius W. (1939). "Massenspektrographische Untersuchungen an Wasserstoff- und Heliumkanalstrahlen (H3+, H2-, HeH+, HeD+, He-)". Annalen der Physik. 426 (5): 473–487. doi:10.1002/andp.19394260506. First 1986? --Stone (talk) 18:07, 21 June 2008 (UTC)[reply]

Even earlier: Coulson, C. A.; Duncanson, W. E. (1938). "Comparison of Wave-Functions for HeH++ and HeH+". Proc. Roy. Soc. A. 165: 90. doi:10.1098/rspa.1938.0047.{{cite journal}}: CS1 maint: multiple names: authors list (link). Perhaps "first studied by Wolfgang Ketterle in 1986" refers to the first spectroscopic studies? I found these two papers by Ketterle: W. Ketterle, H. Figger, and H. Walther (1985). "Emission spectra of bound helium hydride". Phys. Rev. Lett. 55: 2941–2944. doi:10.1103/PhysRevLett.55.2941.{{cite journal}}: CS1 maint: multiple names: authors list (link); W Ketterle, A Dodhy, H Walther (1986). "Bound—free emission of the helium hydride molecule".
