TL;DR: The theory of energy loss, the mean excitation energy, inner shell corrections, energy straggling, multiple scattering effects, and phenomena associated with particle tracks are discussed in this paper.
Abstract: The theory of energy loss, the mean excitation energy, inner shell corrections, energy straggling, multiple scattering effects, and phenomena associated with particle tracks are discussed. Protons, alpha particles, and mesons were chosen because of their penetration dependence on material stopping power. 145 references. (R.E.U.)

TL;DR: In this article, a new physical soft error mechanism in dynamic RAM's and CCD's is proposed, which is caused by the passage of alpha particles through the memory array area.
Abstract: A new physical soft error mechanism in dynamic RAM's and CCD's is the upset of stored data by the passage of alpha particles through the memory array area. The alpha particles are emitted by the radioactive decay of uranium and thorium which are present in parts-per-million levels in packaging materials. When an alpha particle penetrates the die surface, it can create enough electron-hole pairs near a storage node to cause a random, single-bit error. Results of experiments and measurements of alpha activity of materials are reported and a physical model for the soft error is developed. Implications for the future of dynamic memories are also discussed.

TL;DR: In this article, the measured elastic scattering of 24.7 MeV alpha particles from the nuclei O, Mg, Al, Si, Ca, Ma, Ni, Co, Cu, Ge, Zr, Ag, In, Sn, Hf, W, Au, Bi and U has been analyzed using the optical model.

TL;DR: In this article, the interactions of these energetic particles with linear and nonlinear Alfve'n waves generated in the magnetized plasma are reviewed, and the interaction of the alpha particles produced in the nuclear reactions is discussed.
Abstract: In magnetic fusion reactors relying on the burning of deuterium and tritium, sufficient confinement of the alpha particles produced in the nuclear reactions is crucial to sustaining the burning plasma. In this article the interactions of these energetic particles with linear and nonlinear Alfve'n waves generated in the magnetized plasma are reviewed.

TL;DR: In this article, ideas from Griffin's exciton model are combined with those from the nucleon-nucleon scattering approach to nuclear transition times to provide a simple closed-form expression for predicting pre-equilibrium decay phenomena.
Abstract: Ideas from Griffin's exciton model are combined with those from the nucleon-nucleon scattering approach to nuclear transition times to provide a simple closed-form expression for predicting pre-equilibrium decay phenomena, including variation of pre-equilibrium emission with target mass, excitation energy, and initial particle and hole numbers. Time estimates for pre-equilibrium emission are given at several excitations.
