晶体闪烁体的闪烁效应与带电粒子登记效率的提高
Channeling Effect and Improvement of the Efficiency of Charged Particle Registration with Crystal Scintillators
摘要：
强调了考虑部分低能晶体沿低折射率晶轴和晶面沟道效应的重要性（1-10 keV）反冲离子在用NaI（Tl）等类型的晶体闪烁器测量其参数中的应用。由于通道中的核阻止本领与电子阻止本领相比是低的，因此闪烁器的光产额必须是，在给定的情况下比具有更高能量（几十keV或更高）的离子的能量更高，所述离子通过通道外的核碰撞损失其大部分能量。因此，特别是，可以得出结论，在格兰萨索的DAMA/NaI观测中，信号频率在振幅为2-6 keV电子当量的窄范围内的年度调制可能是由于（普朗克天体类型的）超大质量粒子以30-50 km/s的速度从穿越地球的日心轨道入射到地球上。在NaI（Tl）中，这些粒子产生能量仅为2-6 keV的碘反冲离子。
英文摘要：
The importance is emphasized of taking into account the channeling along the low index crystallographic axes and planes of a part of low-energy (1-10 keV) recoil ions in measurements of their parameters with crystal scintillators of the type of NaI(Tl) etc. Because the nucleus stopping power in channels is low as compared with electronic stopping power, the light yield of the scintillator must be, accordingly, higher in the given case than that for ions having higher energy (tens keV and more), which lose most part of their energy via nuclear collisions outside channels. Hence, in particular, it follows that the DAMA/NaI observations in Gran Sasso of the annual modulation of the signal frequency in a narrow range of scintillations with an amplitude of 2-6 keV electron equivalent may be due to incidence onto the Earth of exceedingly massive particles (of the type of Planckian objects) from elongated Earth-crossing heliocentric orbits at a velocity of 30-50 km/s. In NaI(Tl), these particles create the iodine recoil ions with just the energy of 2-6 keV.
