...Coca-Cola); the Grays, who last week sold the venerable Journal (see p. 35); James H. Nunnally (candy) and Steve Lynch, who took fortunes out of Florida's real-estate boom; John K. Ottley and Thomas K. Glenn (banking); Southern Railway's Vice President Robert Baker ("Bob") Pegram 3rd, who is the city's No. 1 railroader. These and their kind once would have lived on Peachtree Street (where dogwood blooms in the spring, but there are no peach trees). Now most of the rich live in lush Druid Hills or out beyond Peachtree Creek. Peachtree Street...

...units to 14 for ordinary nitrogen. After two years of work he and his associates have produced 20 grams of heavy nitrogen in 2½% concentration, 400 grams of lower concentrations. To obtain it they used a 35-ft. vertical tube designed by Columbia's George B. Pegram for the separation of heavy oxygen. The tube contains 1,200 steel cones. A gaseous compound of ammonia, rich in nitrogen, passes up through the tube; some condenses, trickles down and with each fall from cone to cone the concentration of heavy nitrogen becomes richer...
Neutrons have about the same mass as the heart of a hydrogen atom, but they are much smaller. Dr. George Braxton Pegram and his associates at Columbia have set the neutron diameter at one ten-trillionth of an inch. Unlike electrons, positrons, protons and deuterons, neutrons have no electric charge. Hence they make splendid projectiles for bombardment since they are not repelled by the positive charges on the atomic nuclei. Alpha particles knock neutrons in quantity out of beryllium and other light elements at speeds up to 30,000 miles per second. When the neutron hits a nucleus it either...
Before they could reach that conclusion even with the powerful wave mathematics developed by Germany's Erwin Schrodinger, Drs. George Braxton Pegram, John R. Dunning and Isidor Isaac Rabi had to lead their particles like circus animals through a complex series of hoops & hurdles. Beryllium powder was placed in a glass tube containing the radioactive gas radon. Alpha particles from the radon knocked neutrons out of the beryllium. First hurdle was a metal ring which deflected part of the neutron beam toward a cylindrical detection chamber less than an inch across, a half-inch deep. The chamber...
