(1) NASA plans to launch a satellite to study cosmic rays.
(2) Deep space, however, is saturated with cosmic rays.
(3) A stray cosmic ray might do the same thing.
(4) We are continuously bombarded by cosmic rays, atomic particles ejected by distant stellar catastrophes.
(5) If mutagens like cosmic rays are present then all normal mutation rates are boosted.
(6) Tritium can be produced naturally from cosmic rays reacting with the atmosphere.
(7) The characteristics of hadron component in the cosmic ray high energy ? ? - ray families are presented.
(8) Cosmic ray is high - energy particle ray coming from outer space.
(9) During the 1970s, attempts were made to use cosmic ray spallation to produce deuterium. These attempts failed to produce deuterium, but did unexpectedly produce other light elements.
(10) These cause spallation when a cosmic ray (e. g. a proton) impacts with matter, including other cosmic rays.
(11) Voyager 2: Low - Energy Charged Particles, Cosmic Ray Subsystem, Magnetometer, Plasma Wave Subsystem and Plasma Subsystem.
(12) Cosmic ray spallation produces some light elements such as lithium and boron. This process was discovered somewhat by accident during the 1970s.
(13) Using Monte - Carlo method, the propagation of cosmic ray hadrons throughatmosphere is simulated.
(14) This paper describes the control system of Zhengziou Cosmic Ray Air Shower Array.
(15) Voyager 1: Low - Energy Charged Particles, Cosmic Ray Subsystem, Magnetometer and Plasma Wave Subsystem.
(16) Sense organs for lunar and planetary influences, for atmospheric pressure and cosmic rays are as yet purely hypothetical. 2.
(17) This occurs in the upper atmosphere when neutrons produced by cosmic rays interact with nitrogen atoms.
(18) As noted earlier, water is the most useful shielding material against cosmic rays and solar protons.
(19) These minerals receive radiation both internally, from the ceramic, and externally, from the burial environment and cosmic rays.
(20) Glaser switched his area of research from bubble chambers and cosmic rays to molecular biology and biophysics.
(21) These isotopes begin to decay as soon as the meteorites enter the Earth's atmosphere, where they become shielded from cosmic rays.
(22) Extensive Air Shower ( EAS ) happens when a cosmic ray enter Earth's atmosphere.
(23) Going this deep would help reduce the background signals from cosmic ray muon particles.
(24) Based on an analysis of the accumulated data of the cosmic ray experiments, find that inelasticity K decrease with energy as 0.
(25) Cosmic ray spallation is a form of naturally occurring nuclear fission and nucleosynthesis. It refers to the formation of elements from the impact of cosmic rays on an object.
(26) Isotopes of aluminum, beryllium, carbon ( carbon-14 ), chlorine, iodine and neon, are also formed through cosmic ray spallation.
(27) A cloud chamber experiment is described, in which the angular distribution of secondary particles produced in nuclear interaction by high energy cosmic ray particles with paraffin has been studied.
(28) The reconstruction method of muon tracks in the L 3 Cosmic Ray Experiment has been studied.
