Data on Particles and Resonant States, 1967

This data survey is an updating (at the end of 1966) of that of October 1965 (Rosenfeld et al. Rev. Mod. Phys. v. 37 (1965) pp. 633-651). An intermediated version was distributed at the XIII International Conference on High Energy Physics held at Berkeley in August and September 1966. The final version has been compiled since the Conference, and will be published in Rev. Mod. Phys., January 1967. This is an updating, to Aug. 1967, of our January compilation [Rev. Mod. Phys. 39, 1 (1967)]. This edition will not be published; it, and separate wallet sheets, will be distributed at the Heidelberg Conference. Data on the properties of leptons, mesons, and baryons are listed, referenced, averaged, and summarized in tables and wallet cards. The data survey is an updating of that of October 1965 (Rosenfeld et al. Rev. Mod. Phys. v. 37 (1965) pp. 633-651). An intermediate version was distributed at the XIII International Conference on High Energy Physics held at Berkeley in August 1966. This time a large number of early data and references have been deleted from the listings; these pioneer works can be found in any earlier edition.
