Protons were observed in counters filled with CH. The size distribution of ionizing events was determined. Coincidences between neutron counts and shower counts were observed, suggesting a connection between the neutrons and the soft component. Estimates are given of the rates of production in various...

Atoms consist of a nucleus, which is made up of protons and neutrons, surrounded by electrons in shells. The characteristics of an atom are determined by the number of protons and electrons it has. If two atoms have the same number of protons and electrons, they’re the same element. For...
The former features a high-energy reference mixed field with several radiation types, including neutrons, photons, protons, pions, electrons and muons34; the latter is an 18 MeV medical cyclotron used for research activities by the group of the University of Bern, as well as for commercial ...
(fast protons, neutrons, and electrons) that impact upon elements in the rock's crystals, splitting or attaching to the atoms to make new isotopes (i.e.,3He,10Be,14C,21Ne,26Al,36Cl) (Gosse & Phillips 2001). With a known production rate of these isotopes, one can calculate how long...
We are literally empty. We are made up of atoms, but protons, neutrons, and electrons only make up one-fiftieth of one percent of the space in an atom. In addition to your physical body, you must keep your emotional body, mental body, and spiritual body healthy and exercise them on a...
Neutron yields from several targets bombarded by deuterons, protons, neutrons, and He3ions with energies of hundreds of Mev were measured by detecting the ... WE Crandall,GP Millburn - 《Journal of Applied Physics》 被引量: 13发表: 1958年 A study of inelastic interactions of deuterons and al...
The scattered electrons were detected with a magnetic spectrometer of the A1-collaboration. To detect the recoil neutrons in coincidence with the electrons, a nucleon detector was installed. It consisted of a plastic scintillator array inside a heavy lead shield. Exploiting beam helicity asymmetries ...
Particles were tracked as long as their energy exceeded the following limits: 0 eV for neutrons; 1 keV for electrons and photons; 1 MeV/amu for the hydrogen and helium isotopes. In the MCNPX simulations standard settings of the program were used, with the exception of the EFAC setting, ...
Given that electrons of 3 GeV are present, the neutron field originated may span from thermal up to 3 GeV, more than 12 decades in energy, with significant presence of high energy neutrons. Track detectors provide a reading M of the number of recorded particles per unit surface, somewhat ...
