| + | Dongming summarized the goals for our working group with the emphasis on the following aspects: 1) (alpha, n) neutron yield calculations; | ||
| + | |||
| + | Jodi's group is working on the calculation of (alpha, n) neutron yield for common-used materials through SOURCES. Cu, PMT glass, Ti, Poly and so on have been investigated. Dongming suggested to do one more calculation on Teflon. Chao commits to provide the composition of Teflon. | ||
| + | |||
| + | Another common interest is to track down the reason which caused the discrepancy between USD web data base and SOURCES. As the first step, Chao agrees to provide the cross section data of alpha interacting with Copper. Then Silvia will run it through SOURCES to nail down if the difference coming from the cross section itself. | ||

| + | Assignment taking: | ||
| + | * (alpha, n) calculation and adding Th228 and radon decay chain --- Chao | ||
| + | * compare USD web database and SOURCE --- Chao, Jodi, Silvia, Hang | ||
| + | * validation of (alpha, n) calculation --- Chao, Jodi | ||
| + | * implement the reaction to Geant4 --- we prefer Geant4 guys to handle it | ||
| + | * Radiogenic background (external) data sheet for Homestake Mine --- Iseley, Jason, Wenzhao | ||
