 Summary notes: Summary notes:
  
-   * Chao is still working on the (a, n) calculation ​for Th228 and Radon decay chain. ​  +   * Chao completed calculation of (a,n) neutron yield for all materials from Th228 decay chain. He will apply it to Radon decay chain and represent the results at next meeting  ​ 
-   ​* ​Huang and Silvia ​compared ​the cross section data for (a,n) in Copper between Empire and Talys provided by Chao. They conclude the over all cross section data agree each other pretty well. Chao point out the comparison only limited to the total cross section which cannot say the structure is identical. in order to do the detailed comparison we should compare a) the differential cross section; b) the stopping power data; c) the formula to calculate the neutron yield.  +   ​* ​According to the discussion, ​Silvia ​will include the comparison of the (a,n) differential cross section ​between SOURCES and TALYS for Copper target.  
-   * The calculation ​for (a, n) neutron yield in Teflon is done by Chao using USD web database. we are waiting for the results from SOURCES code.  +   * For the background data sheet, Jason is doing the measurement using the germanium detector at 4850ft level right now. He promise ​to present part of results by next meeting.  
-   * For the background data sheet, Jason is doing the measurement using the germanium detector at 4850ft level right now. He commits ​to give the report in next meeting. Once we get the gamma ray measurement results from him, we can combine the data from NaI detector which we did last year at the same level. we should be able to make a comparison table and post it online.  +   ​* ​Silvia will report ​the validations ​of SOURCES ​code by next meeting.
-   ​* ​Chao reports ​the thought on validation ​of (a, n) calculation using AmBe measurement. Jodi mentioned ​SOURCES ​already have this validation done in the document. we hope she can report the result to see how they did the calculation+
