Repulsive Core and Interaction Energy in Proton-Proton Scattering.
ResearchPublished 1969
ResearchPublished 1969
Interaction energy between two protons is computed from high-energy elastic cross sections at 60 deg and 90 deg, using an optical model. The repulsive core becomes important for separation less than 0.3 Fermi. Exponential dependence of high-energy cross sections is shown to predict repulsive forces at small separation. 10 pp. Refs.

This publication is part of the RAND paper series. The paper series was a product of RAND 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.
