D -- CONTINUATION OF PROGRAMMING ASSISTANCE FOR ATOMIC AND MOLECULAR DATABASES SOL 53SBNB967005 DUE 103098 POC Diane M. Loeb, (301) 975-6399 WEB: NIST Contracts Homepage, http://www.nist.gov/admin/od/contract/contract.htm. E-MAIL: NIST Contracts Office, Contract@nist.gov. The National Institute of Standards and Technology (NIST), Atomic Physics Division intends to negotiate on a sole source basis with Svetlana Kotochigova, 5318 Crestledge Lane, Rockville, MD 20853 for the continuation of programming assistance for atomic and molecular databases. This is a follow on effort of Order Number 43NANB808858 for the creation of theoretical models to calculate the electronic structure of xenon molecules in support of experimental programs in ultracold collisions. This requirement is for a nine month period of performance. FOB Destination. No solicitation package will be issued. A Request for Quotation (RFQ) will be issued to Ms. Kotochigova. The Contractor is the only individual capable of performing this service because it requires detailed knowledge of the xenon atomic system, and the relativistic theoretical models and software codes previously developed by the contractor. It would not be possible for another individual to achieve this degree of expertise in the time requiredfor the completion of this contract. The anticipated award date of the contract is on or around 30 days from the date of this notice. In accordance with FAR 5.207(e)(3), Numbered Note 22, DOES NOT APPLY. Note 26 does apply.
