A fixed scintillation counter was used to detect and hence allow measure- ment of the range of 4.88M eV α-particles emitted from a 209P o source in air. The dependence of the range on the geometry of the apparatus was also investigated. The range of alpha particles in air was ...

The stopping power, dE dx, the range, R, and the energy straggling, < ΔE 2>, for α-particles in UC and (U, Pu)C were measured in the energy range between 1 and 5 MeV using three different techniques: carbide layers of known thickness were evaporated on thin α-sources; thin α...
As shown in Figures 3 and 4, the range of alpha particles in copper and germanium elements has been calculated using equation (8) after substituting equation (16) into it. The energy range increases linearly with energy as ionization and excitation. It is noted that the range is very small...
Short-Range alpha-Particles from Oxygen, Nitrogen and Fluorine Bombarded with ProtonsTHE bombardment of fluorine by protons leads to the emission of astrong γ-radiation, for which the excitation curve shows well-defined resonances. In a letter by Dee, Curran and Strothers, in which the nature ...
Long-range alpha particles emitted in the photofission of 235U with 20-MeV bremsstrahlung were measured. The binary to long-range alpha particle ratio, 〈Eα〉, and full width at half maximum (Eα) were deduced.NUCLEAR REACTIONS, FISSION 235U(γ,F), Eγmax=20 MeV, measured: Long-range ...
In this work, a robust stand-off alpha detection method using the secondary effects of alpha radiation has been sought. Alpha particles ionise the surrounding atmosphere as they travel. Fluorescence photons produced as a consequence of this can be used to detect the source of the alpha emissions...
Long-range alpha detector (LRAD) Historically, alpha detectors have been limited by the very short range of alpha particles in air and by relatively poor sensitivity, even if the particles... MacArthur, D. W,McAtee, J. L 被引量: 46发表: 1991年 ...

The angular distribution of long-range alpha particles from the reaction 15N(p, ±) has been investigated over the range 230 kev-960 kev proton energy. It is found that the levels in 16O formed by resonant capture of protons of energy 340 kev and 1050 kev have spin and parity (0, +)...
