Neutron and Charged-Particle Induced Cross Sections for Radiochemistry in the Region of Bromine and Krypton

Abstract

We have developed a set of modeled nuclear reaction cross sections for use in radiochemical diagnostics. Systematics for the input parameters required by the Hauser-Feshbach statistical model were developed and used to calculate neutron and proton induced nuclear reaction cross sections in the mass region of bromine and krypton (34 ≤ Z ≤ 37, 40 ≤ N ≤ 47).

Modeled Neutron and Charged-Particle Induced Nuclear Reaction Cross Sections for Radiochemistry in the Region of Yttrium, Zirconium, Niobium, and Molybdenum

“…This optical potential has also produced favorable comparisons to measured total neutron cross sections in other regions of the periodic chart (Hoffman et al 2004a;Hoffman et al 2004b;Hoffman et al 2004c;Kelley et al 2005;Kelley et al 2006). Further evaluations are provided in (Koning & Delaroche 2003).…”

“…Previous papers treated the regions of bromine and krypton (Hoffman et al 2004a), iodine and xenon (Hoffman et al 2004b), samarium, europium, and gadolinium (Hoffman et al 2004c), scandium, titanium, vanadium, chromium, manganese, andiron (Kelley et al 2005), arsenic (Kelley et al 2006a), and nickel, copper, and zinc (Kelley et al 2006b). Here we focus on reactions proceeding on targets of yttrium, zirconium, niobium, and molybdenum.…”

“…(Bauer 2003). The modified nuclear level schemes for the bromine, krypton, and rubidium isotopes can be found in (Hoffman et al 2004a). The remaining modified schemes, including level energies, spin and parity assignments, and γ-ray branching ratios, may be found in appendix B.3.…”

“…The following figures present our modified level schemes, up to 25 levels. The modified level data for bromine, krypton, and rubidium isotopes may be found in (Hoffman et al 2004a). In these plots, the level energy is listed on the right hand side, and the spin and parity of the level on the left.…”

Modeled Neutron Induced Nuclear Reaction Cross Sections for Radiochemistry in the region of Iriduim and Gold

“…Previous papers treated the regions of bromine and krypton (Hoffman et al 2004a), iodine and xenon (Hoffman et al 2004b), samarium, europium, and gadolinium (Hoffman et al 2004c), scandium, titanium, vanadium, chromium, manganese, and iron (Kelley et al 2005), arsenic (Kelley et al 2006a), nickel, copper, and zinc (Kelley et al 2006b), and yttrium, zirconium, niobium, and molybdenum (Hoffman et al 2006c). Here we focus on neutron-induced reactions proceeding on targets of iridium and gold.…”
