Abstract
Abstract: The ratio of the structure function F2n/F2p (x) has been measured in deep inelastic scattering of 274 GeV muons on hydrogen and deuterium targets exposed simultaneously to the beam. The results were obtained from 0.3 (0.6) million events from hydrogen (deuterium) in the range 0.004

The results were obtained from 0.3 (0.6) million events from hydrogen (deuterium) in the range 0.004 >x> 0.8 and 1 >Q2> 190 GeV2. At x > 0.25 both the statistical and the systematic error is below 2%. Implications for parton distributions and for the σw/σz production cross section ratio in pp collisions are discussed. When compared to other results obtained at lower energies, the data indicate a Q2 dependence of the ratio.</abstract><qualityIndicators><refBibsNative>true</refBibsNative><abstractWordCount>102</abstractWordCount><abstractCharCount>618</abstractCharCount><keywordCount>0</keywordCount><score>8.224</score><pdfWordCount>5078</pdfWordCount><pdfCharCount>18770</pdfCharCount><pdfVersion>1.2</pdfVersion><pdfPageCount>7</pdfPageCount><pdfPageSize>533 x 742 pts</pdfPageSize></qualityIndicators><title>Measurement of the neutron and the proton F 2 structure function ratio</title><pii><json:string>0370-2693(90)91270-L</json:string></pii><corporate><json:item><name>New Muon Collaboration (NMC)</name></json:item></corporate><genre><json:string>research-article</json:string></genre><host><title>Physics Letters B</title><language><json:string>unknown</json:string></language><publicationDate>1990</publicationDate><issn><json:string>0370-2693</json:string></issn><pii><json:string>S0370-2693(00)X1211-7</json:string></pii><volume>249</volume><issue>2</issue><pages><first>366</first><last>372</last></pages><genre><json:string>journal</json:string></genre></host><namedEntities><unitex><date><json:string>1990</json:string></date><geogName></geogName><orgName><json:string>Paul Scherrer Institute, CH</json:string><json:string>Netherlands Max-Planck Institute</json:string><json:string>Institute for Nuclear Studies, PL</json:string><json:string>Indiana University</json:string><json:string>University of Melbourne</json:string><json:string>Oxford University</json:string><json:string>Switzerland University</json:string><json:string>Carnegie Mellon University, Pittsburgh</json:string></orgName><orgName_funder></orgName_funder><orgName_provider></orgName_provider><persName><json:string>N.
