"Big Science" Descriptor : Nuclear physics 



Description of Facility/Instrument ; The cyclotron can accelerate all 

 Ions from hydrogen through krypton to energies above the Coulomb 

 barrier for targets as heavy as uranium. The maximum energy Is 

 35 million electron volts per nucleon. The basic research pro- 

 gram Is focused In four major areas: Investigation of heavy Ion 

 reaction mechanisms; production and study of exotic nuclei far 

 from stability; structure of nuclei at high angular momentum; and 

 studies of spin-polarization effects and basic symmetry princi- 

 ples in nuclear Interactions.

Because nuclear physics is an international activity, 

 with knowledge freely shared among its practitioners, this 

 laboratory has extensive interactions with people and in- 

 stitutions in foreign countries. 



More than 95 percent of researchers working at DOE 

 nuclear physics accelerators are from U.S. institutions. On 

 approximately equal and reciprocal bases, U.S. nuclear sci- 

 entists use foreign facilities. 



In connection with a scientific exchange program with 

 the Jagellonian University, Cracow, Poland, a 60-inch 

 diameter scattering chamber was constructed [on a National 

 Science Foundation (NSF) grant] and moved to the 88-Inch 

 Cyclotron where it is now in use. 



There is a formal exchange agreement between LBL and 

 CNRS (France); a cooperative research grant with scientists
