A -- INVESTIGATION OF THEORIES OF PHOTOASSOCIATION SOL 50SBNB0C1078 DUE 090600 POC Marsha Rodgers, (301)975-6398, e-mail Marsha.Rodgers@nist.gov, Fax (301)963-7732, Contracting Officer Sandra L. Febach 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) intends to negotiate on a sole source basis with the University of Rochester, Rochester, New York for services to investigate pulsed-laser photoassociation processes in ultracold gasses, in which atoms are chemically bound to form molecules using light. The contractor shall modify NIST equipment for these measurements, demonstrate the operation of the modified equipment and perform measurements of the efficiency of molecule production as a function of laser parameters and of the parameters of the atomic gas sample, and compare these measurements with continuous-wave experiments. F.O.B. Destination, Gaithersburg, Maryland. The period of performance is one year from date of award. There is also an option for an additional period of one year. This is a sole source with the University of Rochester because they have expertise in the area of photoassociation spectroscopy with pulsed lasers in the group of Professor Ian Walmsley, Institute of Optics. This group has had long-term experience with pulsed-laser technology and has been preparing to study photoassociated in laser-cooled gases. As such, they are aware of all the unique considerations that both pulsed lasers and ultracold gases bring to the photoassociation problem. The University of Rochester is uniquely qualified in this respect, being the only institution in the country with a developing expertise in the new area of pulsed photoassociation. Interested persons may identify their interest and capability to respond to the requirement . This notice of intent is not a request for competitive proposals. However, all proposals received within 45 days after date of publication of this synopsis shall be considered by the Government. A determination by the Government not to compete this proposed contract based upon responses to this notice is solely within the discretion of the Government. Information received will normally be considered solely for the purpose of determining whether to conduct a competitive procurement. See Notes 22 and 26. Posted 07/21/00 (W-SN477532). (0203)
