A new experimental approach was developed that can reduce the uncertainties in astrophysical rapid proton capture (rp) process calculations due to nuclear data. This approach utilizes neutron removal from a radioactive ion beam to populate the nuclear states of interest. Excited states were deduced by the gamma-decay spectra measured in a semiconductor(More)
One of the difficulties in studying previously uncharacterized neutron-rich nuclei with transfer reactions is in identifying the peaks which are due to excitation of the ground state of the nucleus in question. If the spectra are not absolutely dean, then the background may obscure the peak, or fluctuations in the background may cause a spurious peak to(More)

We present outcomes from curricular changes made to an introductory calculus-based physics course whose audience is primarily life sciences majors, the majority of whom plan to pursue postbaccalaureate studies in medical and scientific fields. During the 2011-2012 academic year, we implemented a Physics of the Life Sciences curriculum centered on a draft(More)

The ground state Q value of the reaction 'sNi(p, m. )' Zn has been measured with E~= 190 MeV. The measured Q value was —144.735(40) MeV and the cross section at 30 deg was found to be 0.080(20) nb/sr. Also measured was the low-lying level structure of Zn and an upper limit on the reaction cross section for ~Ca(p, m ) going to the ground state of 4'Ti. The(More)
