Title: Tungsten fragmentation in nuclear reactions induced by high-energy cosmic-ray protons

Abstract

Tungsten fragmentation arising in nuclear reactions induced by cosmic-ray protons in space-vehicle electronics is considered. In modern technologies of integrated circuits featuring a three-dimensional layered architecture, tungsten is frequently used as a material for interlayer conducting connections. Within the preequilibrium model, tungsten-fragmentation features, including the cross sections for the elastic and inelastic scattering of protons of energy between 30 and 240 MeV; the yields of isotopes and isobars; their energy, charge, and mass distributions; and recoil energy spectra, are calculated on the basis of the TALYS and EMPIRE-II-19 codes. It is shown that tungsten fragmentation affects substantially forecasts of failures of space-vehicle electronics.

  • A statistical nuclear fragmentation model is used to calculate the charge distributions and energy spectra of heavy ({ital z}{gt}4) fragments produced in 1 GeV per nucleon collisions of cosmic-ray {sup 12}C and {sup 16}O with the large-scale integration devices materials: {sup 16}O, {sup 28}Si, {sup 70}Ga, {sup 75}As, and {sup 197}Au. Results for {sup 56}Fe+{sup 12}C at 980 MeV per nucleon are also presented and compared with available data. Calculated charge distributions show a clustering pattern into three {ital z}-number groups while kinetic-energy spectra reveal soft shapes over a 100-MeV range. Charge-distribution and energy-spectrum absolute cross sections from {sup 16}O-inducedmore » fragmentation of {sup 28}Si are 1--2 orders of magnitude larger than those from {sup 12}C-induced fragmentation.« less
  • Gamma rays from solar-cosmic-ray-produced nuclear reactions in the earth's atmosphere are observed by balloon-borne NsI(Tl) scintillation detectors. An attempt is made to understand the processes that lead to gamma -ray production, and the total cross section for gamma -ray production in air by protons of 30 to 300 Mev is calculated to be sigma /sub gamma / approximately 940 x 10/sup -17/ cm/sup 2/. Assuming that the information abou t the solar proton spectrum obtained from the directly measured protons above 110 Mev can be applied to protons below 110 Mev, the minimum energy with which the protons arrive overmore » Minneapolis during the storm is estimated. Such estimations during the May 12, 1959, event show that solar protons of energy as low as 30 to 40 Mev are allowed at the middle-latitude station of Minneapolis. (auth)« less
  • In a fragmentation or spallation reaction a target nucleus is hit by a high-energy projectile (proton or heavy ion). In the fast step of the reaction highly excited intermediate nuclei, the prefragments, are formed. They decay to the particle stable final fragments in a second step. We treat the first step in Glauber theory. For the decay chain we propose a master equation and solve it by converting it to a differential equation. Analytical solutions are obtained. They clarify the underlying physics: The mass yield curve sigma (A) of the final fragments is directly related to the distribution of excitationmore » energy in the prefragments. The isobaric cross sections sigma(A,N-Z) for fixed A are dominated by the level density of the final fragment at its lowest particle threshold. Some properties of the target, like its neutron excess, enter via a memory factor. The formulas are successfully compared to the data.« less
  • The fraction of $sup 149$Tb activity recoiling out of a gold target into the forward (F) and backward (B) directions was determined in irradiations with protons of 1, 3, 11.5, and 300 GeV. The values of F/B decreased from 9.6 at 1 GeV to 2.4 at 300 GeV. The values of 2W (F+B) decreased from 1.24 mg of Au per cm$sup 2$ at 1 GeV to 0.89 mg of Au per cm$sup 2$ at 300 GeV, where W is the thickness of the gold target. These results were analyzed in terms of the standard two-step model for the reaction. Themore » momentum transfer, which occurs in the first step, decreases with the energy of the incident protons. The average kinetic energy of the $sup 149$Tb nuclei in the second step is 3.9+-0.1 MeV for protons in the energy range from 0.7 GeV (earlier work) to 300 GeV. The constancy of this value indicates that the reaction mechanism is essentially unchanged over this range of bombarding energies. (AIP)« less
