...Pauli, on his part, observed that when beta rays pop away from a substance like radium, the substance loses a certain amount of energy. But the energy of the departing rays is always less than the substance's energy loss. What happens to the difference? Dr. Pauli surmised that it rides away on what he called a neutron...
...Anthony Tuve of the Carnegie Institution (TIME, Feb. 8), which measures a current of one electron per second, smallest current measured so far; 2) the device (including thyratron tubes) of Dr. Wynn Williams of Cambridge University, England, which counts alpha particles (nuclei of helium atoms) as they explode from radium at a speed of 12,000 mi. per sec., and ten microseconds apart. (A microsecond is one-millionth of a second.) Dr. Kenneth T. Bainbridge of Bartol Laboratories, Philadelphia, again described his two-ton mass-spectrograph which is sensitive to one-trillionth of a trillionth of an ounce (TIME...
...Most important mineral discovery in many years," noted Hugh S. Spence of the Canadian Department of Mines, are two veins of pitchblende at Great Bear Lake, Canada. One gram of radium, worth about $70,000, is produced from six and a half to 13 tons of pitchblende. Canada expects to break the Belgium monopoly of African radium as soon as railroads and highways can be built to Great Bear Lake...
...three young men projected radium's beta (high speed electrons) and gamma (penetrating X-rays) rays out of that mica window. Left for duplication were radium's alpha particles, the nucleus of helium...
...helium nucleus of four protons is clumsy chain-shot for atomic bombardment. Drs. Tuve, Hafstad & Dahl now surpass radium by shooting single protons from their gun. By means of a cloud chamber they are now able to see and photograph the stream of protons from their machine. The effect looks like a stubby shaving brush with bristles 1.6 in. long. Each bristle is the path made by a proton only one 10,000th of null millionth of an inch in diameter...
