optical energy (by Schwinger theory) (([dE? D sub E?])/([d(lambda)? d sub lambda?)) max at 70 angstroms. (((([dE? d sub E?)/([d(lambda)? d sub lambda?))(70(A) degrees)) / ((([dE? d sub E?)/([d(lambda)? d sub lambda?))(6000(A degrees)))) ~70,000. Very little work in the literature on 50-200 [H? A?] degrees optical absorption due to lack of a light source. May be useful for absolute line intensity calibration in far U.V. ------------------------------------------------------------------------ Moyer (Berkeley) Evidence for neutral meson : mean life of (pi degrees) (L 2 x (10 exponent -13)) seconds (pi -) mass 271.4 +- 2.5 [me?]. (pi exponent 0) mass 261 +- 4 [me?].
