Neutron scattering from 208Pb at 30.4 and 40.0 MeV and isospin dependence of the nucleon optical potential
R. P. DeVito, Dao T. Khoa, Sam M. Austin +2
Analysis of data involving nuclei far from stability often requires optical potential (OP) for neutron scattering. Since neutron data is seldom available, while proton scattering d…

Editorial: Physical Review C in its Fortieth Year
Sam M. Austin, Benjamin F. Gibson
This year, 2010, is the 40th anniversary of Physical Review C as a separate section of the Physical Review. We write here with a double purpose: first, to describe how PRC has evol…
Spectroscopy of 13B via the 13C(t,3He) reaction at 115 AMeV
C. J. Guess, R. G. T. Zegers, B. A. Brown +13
