Low Energy Nuclear Reactions: Experimental Evidence and Theoretical Limitations

摘要

The possibility of extracting energy from nuclei atrnlow temperatures has many attractions. That is one of thernreasons why the 1989 announcement of "cold fusion"rncaused such excitement. Over 3000 papers have beenrnwritten on the subject to date. The field is now widelyrncalled LENR for Low Energy Nuclear Reactions, becausernmany experiments show that diverse nuclear reactionsrnother than fusion can occur. This paper has two purposes.rnThe first is to marshal for the first time, and categorize, allrnthe types of evidence that nuclear reactions do indeedrnoccur at low energies (temperatures) in condensed matter.rnThe second is to show by calculations that LENR cannotrnbe due to only energetic point reactions, as in the nuclearrnreactions produced by beams or within multi-millionrndegree plasmas.
