Primordial Nucleosynthesis: Beyond the Standard Model,t, and otherwise unattainable, constraints on many aspects of particle physics. Finally, there is tentative evidence which suggests that the Standard Big Bang (SBB) model is incorrect in that it cannot reproduce the inferred primordial abundances for a single value of the baryon-to-photon ratio.

Experimental Determination of Stellar Reaction Rates,s energy and . the cross section of the reaction. As a star evolves, its temperature changes, and hence the reaction rate . must be evaluated for each temperature of interest. This evaluation requires . to be known in the range from nearly zero energy to high values (see below).

Nuclei in Cosmic Rays,some 50 km east of Berlin . The results of the measurements during this flight showed unambiguously that the ionization of air passed through a flat minimum between 1000 and 2000 m above ground and then increased steeply to values much above ground level. This clearly indicated an extraterrestrial source of radiation.
