A brief review of the theoretical water-boiler reactor-power transfer function is presented as background for the experimental determination of the ratio of effective prompt neutron lifetime to the effective fraction of delayed neutrons, 1/beta. The preparation and performance ot the experiment are discussed with special emphasis on equipment procedures, and measurement errors. The results, which strongly support a seven-delay-group model of the reactor, are presented and compared with theoretical six-and seven-group models. The experiment indicates qualitative values of the seventh-group constants, and it also indicates an 1/beta = 7.7 plus or minus 0.3 msec valid for all but short- period …
