The long-lived high-spin isomer of {sup 178}Hf, with T{sub 1/2} = 31 y and I{sup {pi}} = 16{sup +}, presents a unique opportunity for a projectile and/or target in nuclear and atomic physics. Various aspects in using {sup 178m}Hf for this purpose are discussed in this paper. One possible production mode, the irradiation of Ta with protons, was investigated. Cross sections of {approximately}40 and {approximately}200 {mu}b were found for proton energies of 46 and 92. 5 MeV, respectively. First ideas for a possible isomeric enrichment procedure by selective laser deflection are presented. 14 refs., 3 figs., 1 tab.
