摘要：

Photoconductivity spectra of the interstitial Mg double donor have been studied. A strong Fano resonance structure has been observed for the singly ionised centre and its assignment is discussed in detail. Our results show that the electron-phonon interaction, previously reported for many substitutional centres in silicon, is also observed for interstitial centres. Furthermore, two Mg-related donors with activation energies of 55 and 93 meV have been studied and their excited states have been found to agree with EMT.
