Various light-and heavy-ion reactions, 20 < E i 100 MeV, have been used to study the reaction dependence of a-decay widths for *Be*(2+, 2.9 MeV) and '60*(1-, 9.6 MeV). Although slight differences (< 20 %) are found for the observed line shapes (F), the resonance widths inferred (F,) are self-consistent and indicate little if any reaction dependence (i 10 %). Near a decay threshold one may expect F < FR by 20 % or more, however, and thus care must be taken in comparing decay widths inferred from nuclear reactions with those from scattering resonances. Reduced formal a-decay widths of y: = 68Ok 100 keV (s = 4.8 fm) and 7: = 350+50 keV (S = 5.4 fm), corresponding to 19: = 0.50 and 6: = 0.49 are deduced for sBe*(2+, 2.9 MeV) and 16G*(]-, 9.6 MeV) using the nuclear-reaction Fa values and a particular set of a-nucleus potentials.
