自然界存在的、应用于实验的其他类型辐射有电子(electrons)、质子(protons)、α粒子(α-particles)、中子(neutrons)、负π介子(negative π-mesons)及重离子(heavy charged ions)。其中一些也应用于放射治疗,但有些在放射诊断方面的潜力还没有被开发。 重放射性核素释放α...
In the context of Big Bang Nucleosynthesis (BBN), the calculation of neutron abundance involves considering the rate of conversion between protons and neutrons, as referenced in [65, 66]. This conversion rate λpn(T) is defined as a combination of various processes: λpn(T)=λ(n+νe→p+...

首先,我们讨论一些基本原理。原子核由一定数量的质子(protons)和中子(neutrons)组成。有一些电子(electrons)围绕着原子核做轨道运动。电子的个数必须和质子的个数完全相等,因为电子的负电荷数需与质子的正电荷数相互抵消。中子,顾名思义,当然是...

Soft errors are transient errors caused by single event effects that occur in microelectronics when highly energetic particles, such as protons, electrons, and neutrons, strike sensitive regions of a microelectronic circuit [1]. Neutron-induced soft errors were observed in airborne computers in 1993 ...
