摘要	Doppler-broadening spectra of positron annihilation radiation of Al, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn and Ga have been measured by using 2-detector coincidence technique. The lower background of the spectrum allows to obtain the contribution of annihilations with core electrons. The experiments show that the background decreases with increasing the distance between the sample and the Ge detector. The magnitude of the peak of the ratio curve of Ni (ratio to Al) increases with decreasing the background of the spectrum. For Ti, V, Cr, Mn, Fe, Co, Ni and Cu, the heights of the peaks in the ratio curves rise with in creasing the number of 3d-electrons.
