If a particle has kinetic energy, K = 60 MeV when its momentum magnitude, p = 100 MeV/c, what is the ratio m/m_e of its mass to the electron mass? What is the kinetic energy of an electron that has the same momentum as a 1.33 MeV Co-60 gamma-ray? A ...
由能量守恒有：E=E1+E0-E2，两边平方得E^2=E1^2+E0^2+2*E1*E0+E2^2-2*E1*E2-2*E0*E2 代入E^2= E0^2+P^2*c^2，E1^2=P1^2*c^2，E2^2=P2^2*c^2整理得 P^2=P1^2+2*P1*E0/c+P2^2-2*P1*P2-2*P2*E0/c (2)又E1^2=P1^2*c^2=(20GeV)^2，E0=0.938...
aElectron volt (eV). A convenient unit of energy for atomic and subatomic systems. It is equivalent to the energy acquired by an electron when it falls through an electric potential of 1 volt. 电子伏特 (eV)。 能量一个方便单位为原子和亚原子的系统。 当它通过1伏特时,电潜力下跌它与电子获取...
We analyzed the energy dependence of electron stopping powers (SPs) calculated for 41 elemental solids from experimental optical data for electron energies between 100 eV and 30 keV. Our analysis was performed with the Hill equation to represent a series of steps in plots of the slopes of Fano...
An electron has the same de Broglie wavelength as the wavelength as the wavelength of a 1.8 eV photon. What is the speed of the electron? 1. An electron has kinetic energy 1.00 eV. Find its wavelength. 2. A photon has...
observed whenEb/Er≥2.2[38, 39]. In practice, time-resolved spectroscopy of lead sulfide,selenide, and telluride QDs has shown MEG thresholds in the rangeEb/Er=2.7–3.0[40–43]. More precisely, the efficiency of MEG has been defined in terms of the QY at a given photon energy,hν[44...
This current spike charges the capacitor even further, resulting in a rapid increase of Vmem to ∼0.34 V (depolarization). The K-OECT, which turns on after a delay enabled by its intrinsic gate capacitance and resistance Rdk, reaches its peak current after Na-OECT has crossed its ...
