提出了一种测量亚MeV到几MeV范围内γ射线能量、方向和偏振的新方法。我们发现，如果前4-5步的反冲电子的能量和位置为4-10 keV（rms），测量范围为1 × 1 × 1 mm ~ 3，则γ射线能量退化过程的第一次康普顿散射可以很高的概率被正确地重建。如果使用硅探测器叠层，我们在没有准直器的情况下得到每个伽马射线约1°（rms）的角分辨率。我们已经开始开发工作，使这样的设备使用2维硅条探测器。
A new method to measure the energy, direction, and polarization of gamma rays in the sub-MeV to few MeV range is proposed. We found that the first Compton scattering of the gamma-ray energy degrading process can be correctly reconstructed with a high probability if energies and positions of recoil electrons are recorded with 4–10 keV (rms) and ∼ 1 × 1 × 1 mm3for the first 4–5 steps. If a silicon detector stack is used, we get an angular resolution of about 1° (rms) per gamma ray without collimators. We have started development work to make such a device using 2-dimensional silicon strip detectors.
