43) BARN
One barn is 10−28 square metres, about the cross-sectional area of a uranium nucleus. The name probably derives from early neutron-deflection experiments, when the uranium nucleus was described, and the phrases "big as a barn" and "hit a barn door" were used. Additional units include the microbarn (or "outhouse")[11] and the yoctobarn (or "shed").[12][13]
