Abstract：
Spectra and angular distributions of the(α,d)reactions on ⁵⁶Fe ⁵⁷Fe and 59Co have been measured with the △E-E telescopic systems and Q3D magnetic spectrometer at a bombarding energy of 35MeV from the HI-13 Tandem,and analyzed with microscopic DWBA.Among the angular distributions of nine levels strongly populated by ⁵⁶Fe(α,d)⁵⁸Co reaction, the experimental data of 6.79MeV and 6.4MeV levels in ⁵⁸Co were analyzed and discussed. The highest stretched configuration (1g_9/2,1g_9/2)₉ was found and J^π=1⁺ of 6.4MeV level was determined for the first time. No isolated stretched states were observed by ⁵⁷Fe ⁵⁹Co(α,d)reactions.This probably means that the strength of the stretched configuration spreads on a number of states.
