VI. ATOMIC BEAM RESEARCH

Prof. J. R. Zacharias R. T. Daly, Jr. R. D. Haun, Jr.

Dr. V. Jaccarino D. S. Edmonds, Jr. J. H. Holloway

Dr. J. G. King H. H. Stroke

The present interests of the atomic beam laboratory are:

1. To exploit the inherent high precision of the atomic beam method. Experi-mental work is being carried out to utilize this accuracy as a primary frequency stand-ard. An apparatus which has a theoretical frequency precision of one part in 1012 is under construction. Another possible application of this work is a better understanding of the hyperfine structure interaction.

2. To investigate the structure of nuclei through a study of the static properties of their ground states. In particular, measurements of the spins, magnetic dipole, elec-tric quadrupole, and magnetic octupole interaction are being carried out on certain nuclei. Information concerning the distribution of nuclear magnetism is also obtained from a study of the hyperfine structure anomaly in various isotopes, and experimental work along these lines is in progress.

The results of measurements of the hyperfine structure of I127 are being prepared for publication.
