Part of a broader investigation concerned with developing practical antineutrino detectors for use against nuclear submarines and rockets, communication by means of neutrino radiation, and a system for monitoring nuclear weapons. An earlier proposal suggested that, although the well-known antineutrino reaction of inverse beta decay might not be useful for these purposes, perhaps some other less well-known reactions might have much larger cross sections. This Memorandum considers the available information on all antineutrino reactions. The study concludes that, at least for nuclear-test-detection purposes, no antineutrino reactions are useful.

This report is part of the RAND Corporation Research memorandum series. The Research Memorandum was a product of the RAND Corporation from 1948 to 1973 that represented working papers meant to report current results of RAND research to appropriate audiences.

Our mission to help improve policy and decisionmaking through research and analysis is enabled through our core values of quality and objectivity and our unwavering commitment to the highest level of integrity and ethical behavior. To help ensure our research and analysis are rigorous, objective, and nonpartisan, we subject our research publications to a robust and exacting quality-assurance process; avoid both the appearance and reality of financial and other conflicts of interest through staff training, project screening, and a policy of mandatory disclosure; and pursue transparency in our research engagements through our commitment to the open publication of our research findings and recommendations, disclosure of the source of funding of published research, and policies to ensure intellectual independence.
