本文用β-NMR研究了12 B注入金刚石后的注入位置和缺陷。在160 ~ 320 K温度范围内，利用在Larmor频率（ν=νL± 200 kHz）附近宽调制的射频测量了~（12）B的维持极化。发现在该温度范围内观察到的极化几乎恒定在约0.9%。该系统的初始偏振度约为8.1%。因此，约10%的被激发的12 B在该频率范围内保持其极化。相反，在本实验中，约90%的未检测到的12 B。
Aβ-NMR study of12B implanted in diamond was performed in order to investigate the implantation sites and the defects. The maintained polarization of12B was measured by use of widely modulated rf around the Larmor frequency (ν=νL± 200 kHz) as a function of temperature from 160 K to 320 K. The observed polarization was found to be almost constant at about 0.9 % in this temperature range. The initial polarization for this system was obtained as about 8.1 %. Therefore about 10 % of the implanted12B maintained its polarization in this frequency range. Conversely, about 90 % of the implanted12B was undetected in the present experiment.
