lackbody whose peak intensity corresponds to the 1420 MHztransition.2-5. Wien generated hydrogen ions by discharge of hydrogen gas at a verylow pressure and determined the e/m(charge/mass) value, whichturned out to be the highest among different gases tested. In 1919,Rutherford bombarded nitrogen with alpha-particles and observedemission of a positively charged particle which turned out to be thehydrogen ion observed by Wien. Rutherford named this particle the“proton”. Fill in the blank in the answer sheet.14 N + 4 He → ( ) + 1 H3
