GAMMA-GAMMA ANGULAR CORRELATION IN NICKEL 60

Abstract

A reinvestigation was conducted of an anomaly in the experimental angular correlation for the gamma-gamma cascade of Ni60. Programs for the CDC 1604 computer have been developed in FORTRAN language for complete data reduction accepting as input the total counts in each channel, the total coincident counts, and other experimental parameters. The program provides for the calculation of the coefficients for a cosine series and a Legendre polynomial series expansion of the least squares fit to the experimental points. Other programs were developed to calculate the corrections for non-point detectors to be applied to the theoretical coefficients, and to calculate coincidence resolving times from data obtained during a large number of runs. Major improvements were made in the equipment to be used in future angular correlation experiments, including the construction and testing of both a slow and a fast coincidence unit.
