<Stuart Freedman> and <John Clauser> measured <polarization> <correlations> between pairs of <photons> emitted in a <calcium> atomic cascade. Comparing coincidence rates at different polarizer orientations allowed them to test a <Bell inequality> adapted to their apparatus; the 1972 results agreed with <quantum mechanics>. Their measurement made a foundational question experimentally concrete, while its interpretation retained assumptions concerning the detected sample and optical efficiencies.<Experimental Test of Local Hidden-Variable Theories by Stuart Jay Freedman and John Francis Clauser>[Abstract and experimental correlation analysis, LBL-392]{ref}
A <physicist> who researched <nuclear physics> and experimentally tested <Bell inequalities>.<Professional profile of Stuart Jay Freedman (newscenter.lbl.gov)>[Opening biography; final biographical paragraphs.]{ref}
