PTOLEMY, a Program for Heavy-Ion Direction-Reaction Calculations

Description: Ptolemy is an IBM/360 program for the computation of nuclear elastic and direct-reaction cross sections. It carries out both optical-model fits to elastic-scattering data at one or more energies, and DWBA calculations for nucleon-transfer reactions. Ptolemy has been specifically designed for heavy-ion calculations. It is fast and does not require large amounts of core. The input is exceptionally flexible and easy to use. This report outlines the types of calculation that Ptolemy can carry out, summarizes the formulas used, and gives a detailed description of its input.

Puerto Rico Energy Center Study: Executive Summary

Description: From introduction: The scope of work of the study was to compile and analyze information on the resources and requirements of the southwestern, southeastern, and north-central coastal regions of the Commonwealth, and assess industrial and agricultural activities which in conjunction with the power and desalting plants, might comprise the energy center complex. The study was also to identify the need for any experimental, pilot or demonstration projects which benefit the practical application of the Energy Center concept in Puerto Rico.

A Pulse Ammeter

Description: A quantizing pulse ammeter has been designed which brackets an input pulse current peak between two preset current levels. These levels are easily selected by calibration circuits contained on the chassis. Readout is presented in the form of a Nixie visual display as well as an output which is suitable for automatic data recording.

Pulse Amplifiers Using Transistor Circuits

Description: From Introduction: "The high frequency response remains important even when pulse shaping is introduced. Pulse shaping is used to improve the time resolution of the system, to minimize overload distortion, or to facilitate the action of discriminating and recording circuits. The amplifier response may be optimized by such shaping, but in general the overall characteristics will be fixed by the particular detector system."
