Hidden Spin-Isospin Exchange
Symmetry S (2021) Nucleons can have two possible spins (up or down) and two different varieties or isospins (proton or neutron). The forces among the nucleons in an atomic nucleus are complicated since nucleons are built from more fundamental components known as quarks and gluons. In some cases, however, the nuclear force reveals itself to be simple and symmetrical, as though the distinction between spin and isospin is lost. |

Glancing into a Nuclear Mirror:
the Fate of Aluminum-26 in Stars (2021) The destruction rate of 26Al by capturing a proton to make 27Si is critical for interpreting the amount of 26Mg observed in the Universe. This research shows that the rate for proton capture on the long-lived 0+ excited state is eight times less frequent that previously estimated. This was accomplished by studying the "mirror" reaction of adding a neutron to the 0+ ground state of 26Si. |

Radii of Mirror Nuclei and the Neutron Matter Equation
of State (2017) The difference in the root-mean-square charge radii of mirror nuclei is shown to be a robust measure of the derivative of the symmetry energy and the neutron equation of state near nuclear saturation density. Due to Coulomb distortion, the neutron skin contains a extra term proportional to the value of the symmetry energy. |

The
Music of Nuclear Energy Level Spacings (2017) The spacings for the complete set of energy levels up to 6.2 MeV in 208Pb have been analyzed in terms of GOE and Poisson distributions. The experimental result is in close agreement with the GOE distribution. It is also in agreement with calculations based on a realistic residual interaction. The energy spacing have been converted into musical notes so that one can hear as well as see the difference. |

A Nuclear
Detective Story (2015) The 30P(p,gamma)31S rapid-proton capture rate is one of the most important reactions that determines the fractions of elements up to calcium that are produced in novae. We are trying to match up the experimental and theoretical level-scheme finger prints for 31S in order to reduce the uncertainty in this reaction rate. |

Collaboration
Between Experiment and Theory (2015) The theory group at the NSCL has expertise in many theoretical methods. Collaboration among the members of group and with the experimental program at the NSCL provide the resources and interactions needed to make advances toward the overall goals of nuclear physics. |
