Further development of the study of quark chemistry begun in P-3814. Negatively charged quarks and antiquarks could induce fusion in light elements, causing nuclear build-up similar to that observed by Alvarez and his colleagues for muon-catalyzed reactions. Unlike muons, quarks slowing to rest in matter should live forever and induce fusion without ever being captured by nuclei, because nuclei cannot carry a nonintegral charge. In the build-up of elements by quark catalysis, the well-known difficulty at atomic number 5 does not arise. About 10 exp (-26) quarks per proton could have produced the 1/10 percent abundance of light elements observed on stellar surfaces by fusion catalysis. The entire energy output of the sun could be produced by 10 exp (-25) quarks per proton catalyzing fusion in a mixture of hydrogen isotopes and helium.

This report is part of the RAND Corporation Paper series. The paper was a product of the RAND Corporation from 1948 to 2003 that captured speeches, memorials, and derivative research, usually prepared on authors' own time and meant to be the scholarly or scientific contribution of individual authors to their professional fields. Papers were less formal than reports and did not require rigorous peer review.
