Berkeley-TF Experiments

The 88" Cyclotron in Berkeley was closed as user facility by DOE at the end of 2003. 

The nuclear physics community at large lost an unique opportunity for experiments with high energy heavy ion beams.

Completed experiments 

Neodymium Isotopes

The first 2⁺ states in Nd isotopes were measured earlier at the Yale tandem.

At the 88" Cyclotron in Berkeley at energies of about 600 MeV the first 2⁺ and 4⁺ states were measured.

3. ⁷⁶Kr
4. In Aug. 2003 the radioactive Krypton isotope 76 was produced at the 88" cyclotron using the reaction ⁷⁴Se(alpha,2n)⁷⁶Kr, extracted, and in a procedure called re-cyclotron method accelerated to 230 MeV.
   Results were reported at the DNP meeting in Oct. 2003 in Tucson, Arizona.
