Spin polarized radioactive B-12, N-12, and Li-8 probe nuclei are implanted in nominally undoped ZnSe at stationary concentrations less than or equal to 10(10) cm(3). These light dopants, one donor and two acceptors, are characterized by beta-radiation detected nuclear magnetic resonance (beta-NMR) measurements. The donor B-12 and the acceptor N-12 show quite similar and rather simple implantation behaviour, the situation is markedly different for the second acceptor Li-8, however. This contrast indicates that in semi-insulating ZnSe the structure of dilute impurities is controlled by individual, element-specific properties.
