Improved Calibration Facility
Aid in redesign of the calibration facility in order to: 1. Reduce the rate of exposure for calibration personnel below 1 mr/hr; 2. Reduce the rate of exposure outside of the 3745 Building; 3. Reduce the risk of breaking radium sources; 4. Improve the efficiency of calibration procedures by: a. Allowing calibration to be done faster; b. Providing several calibration ranges which can operate simultaneously in the present space allowed; c. Allowing instrument survey work to proceed while calibration work is done. A well-type calibration installation is proposed and a brief description of the required shielding is included.

About an Intense-Light, Silent Discharge Tube for the Spectroscopic Examination of Small Amounts of Substances
One of the problems in the spectrographic investigation of the atomic nucleus is to increase the efficiency of the source of light used for the investigation. Using new procedures outlined in the article new elements may be detected through nuclear change.

About the Model of Bacterial Photosynthesis
At the base of photosynthesis of green sulfur bacteria lies an oxidation-reduction reaction of transferring hydrogen from hydrogen sulfide to carbon dioxide, accomplished with the participation of light energy. Based on experiments the author concludes that chlorophyll in the process of photosynthesis plays the role of optical sensitizer.

The Absolute Yield of the Ferrous Sulfate Oxidation Reaction
The absolute yield of the ferrous sulfate oxidation reaction, under the influence of ionizing radiation, has been determined. A polystyrene, parallel plate ionization chamber, filled with argon, nitrogen, or air, was used to measure the energy absorbed per unit volume of the solution through the application of the Bragg-Gray principle. The ionization current was extrapolated to zero chamber spacing. In related experiments the average ionization potential of polystyrene was determined to be 34.3 ev by comparison with argon and nitrogen. The G value obtained in this experiment using the three gases was 15.9 ± 0.5 ions/100 ev, in good agreement with calorimetric and cathode-ray bombardment measurements.

Acceleration Design Studies for Production of High Center-of-Mass Energies
To aid in planning Brookhaven's future program in high-energy physics, we have just completed a summer study on possible experimentation with super-high-energy accelerators and with storage rings. I should like to review a few of our conclusions and to describe an experiment on coasting beams in progress at Brookhaven. First, however, to provide background for this review, I shall present a short history of the past year. During 1962, many proposals were submitted to the United States Government for design or construction of accelerators for energies above 700 Mev. In order to decide which of these proposals should receive support, an advisory panel was set up under the chairmanship of Professor Norman Ramsey of Harvard. Last April this panel submitted its report. During last April the Brookhaven Laboratory received an official authorization to proceed with studies aimed at the recommended storage rings and super-energy accelerator.

The Activation of the Rare Earths by Thermal Neutrons
The present knowledge of artificial radio-activity is more spotty for the rare earths than for any other region of the periodic table. The chief reason for this is the difficulty of obtaining sufficiently pure samples or at any rate such of well-known composition. Rare earthers were investigated through the activation by thermal neutrons.
