A simple model is presented for waves traveling on a vertical rope of uniform density. The waves travel with an upward acceleration of g2. The standing wave frequencies and nodal positions for the modes of oscillation are calculated. The standing wave frequencies form a series of odd harmonics. The results are compared to those derived by Satterly.
The data on the interactions of cosmic-ray protons in nuclear emulsion have been analyzed in light of the results of recent exposures of emulsion to accelerator protons. Plots of (log,, tan 0 ) as a function of the number of evaporation prongs, N , , , display an energy-independent behavior which is exploited to determine the energies of cosmic-ray events. It is found that the energies quoted in the literature are generally too high. The average charged multiplicity is linearly related to N , from 30 GeV to 5 TeV. While a model of nuclear cascading based on direct production is consistent with these data from 30 GeV to 500 GeV, a model proceeding through an ~ntermediate state gives better agreement at cosmic-ray energies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
