We present a simple method for the quantitative analysis of light elements, H, C, N and O, in thin, self-supporting low Z films with MeV protons in one run. Proton-proton scattering is utilized for the detection of hydrogen and backscattered protons are simultaneously analyzed for detecting ...
A stack of Ilford G5 emulsions exposed to the 5.7 Bev proton beam of the Berkeley Bevatron has been searched for disintegrations of silver and bromine nuclei with ejected 8Li fragments, and 91 examples found. The experimental results can be explained qualitatively by assuming that most of the ...
Contributions to the production of 24Na in Al beam monitors due to secondary particles from the interaction of 28 GeV protons with uranium, thorium, and tantalum targets were measured. Per 100 mg/cm 2 of target thickness they were found to be 13% for U and Th, 7.8% for Ta. The ...
222Rn is unstable and decays by losing 6 neutrons and 2 protons. What is the final decay product? A 218Bi B 216Bi C 216Pb D 214Po E 212Tl Write the beta-decay reaction for Cf-255. Write a nuclear equation for the indicated decay of each of the following nucl...
Find the atomic mass and mass number of an atom with 6 protons and 8 neutrons. Identify the isotope that has an atomic number of 76 and a mass number of 192. The average of the total mass of all an element's isotopes is called: a. the isotopic ...
