Objectives

     The goal of the workshop is to initiate a constructive discussion focused on the Surrogate-Reaction technique and its application to nuclear reactions involving unstable nuclear species. The workshop will focus on the need for studying such reactions and the possibilities for determining relevant reaction rates with experimental and theoretical methods. The Surrogate Method will be introduced. The status of experimental methods will be reviewed and opportunities for measurements at current and upcoming radioactive beam facilities will be discussed. The status of theoretical approaches will be examined. Areas in need of experimental and/or theoretical development will be identified and strategies for progress discussed. The potential for making a significant impact with this method will be discussed.

Audience

     The workshop will bring together experts in nuclear theory and experiment. In order to maximize the interaction between these groups and to facilitate the discussions, the workshop will aim at providing introductions into relevant topics and allocate time for discussions and working groups.

Program

Monday January 12	Morning	The Physics of Nuclear Reactions (P) A half-day introductory tutorial. This session will give a general overview of the workshop and provide useful background information to the participants. Topics: reaction theory, direct reactions, compound nucleus, pre-equilibrium, theoretical descriptions, and experimental signatures.
	Afternoon	Applications, Opportunities and Needs (A) This session will motivate the study of reactions on unstable nuclei. Which reactions are important? Why? The importance and potential impact of having reliable reaction cross sections for unstable nuclei will be discussed. Topics: astrophysical processes, fission, stewardship science, rare isotope beams.
Tuesday January 13	Morning	The Surrogate Method- Merging Theory and Experiment (S) Surrogate techniques for obtaining cross sections for hard-to-determine reactions will be presented and discussed. Topics: history of the surrogate method, recent applications, developmental needs, limitations of the technique.
	Afternoon	Experimental and Theoretical Details (D)- Parallel Sessions Two parallel sessions for presentations of both experimental and theoretical techniques and their applications toward the development of the Surrogate method.
Wednesday January 14	Morning	Experimental and Theoretical Approaches and Tools (E+T) Modern experimental and theoretical approaches and tools for determining reactions on unstable nuclei will be discussed. Topics: experimental methods, modern calculations, the promise of rare isotope beams.
	Afternoon	Working Groups (W) Small group discussions on specific aspects of the Surrogate Method. Summaries will be prepared. Each group will have a designated discussion leader and secretary.
Thursday January 15	Morning	Overall Summary and Discussion (O) Summaries from working groups will be discussed. Topics: areas in need of development, strategies for the future, conclusions.
	Afternoon	Workshop Report (R) Preparation of final workshop report by designated report committee.
