Nuclear theory is important in the determination of reaction cross sections and rates for astrophysics in several respects. Firstly, a large number of reactions in astrophysical environments involve highly unstable nuclei which are unaccessible in laboratory measurements. This is especially true for the high temperature plasmas of stellar explosions. Secondly, despite of high plasma temperature...

Radial transport theory for inner radiation zone MeV ions has been extended by combining radial di€usive transport and losses due to Coulomb friction with local generation of D, T and He ions from nuclear reactions taking place on the inner edge of the inner radiation zone. Based on interactions between high energy trapped protons and upper atmospheric constituents we have included a nuclear re...

Reaction measurements on fission products are being planned at both Argonne National Lab and the Facility for Rare Isotope Beams. These indirect experiments produce specific short-lived nuclei via beta decay, subsequent neutron gamma emission studied. Some initial found a surprising overabundance of emission, which theory has yet to explain. To remedy this, we developing an integrated nuclear d...

Optical limit Glauber theory calculations of reaction cross sections, used to deduce nuclear sizes from high energy data, are studied in the case of a deformed projectile ~or target!. We show that a previously applied formula, used to adjust the root-mean-squared radius deduced assuming spherical projectiles, is consistent with results which treat the projectile deformation explicitly within th...
