TL;DR: In this paper, the cross section at 0° for the reaction 14 C(p, n) 14 N has been measured at energies of 200, 300, 400 and 450 MeV using a nucleon charge exchange facility recently commissioned at TRIUMF.

D. Frekers,D. Bohle,D. Bohle,A. Richter,A. Richter,R. Abegg,R.E. Azuma,R.E. Azuma,A. Celler,C. Chan,C. Chan,T.E. Drake,T.E. Drake,K. P. Jackson,J.D. King,J.D. King,C. A. Miller,R. Schubank,R. Schubank,J. W. Watson,J. W. Watson,S. Yen +21 more
TL;DR: In this article, the spin part of the low-lying isovector magnetic dipole transitions in the rotational rare earth nuclei was investigated using intermediate energy proton scattering and the results were consistent with the picture of a predominantly convective excitation.

Complete spin observables for quasielastic proton scattering from 54Fe at 290 MeV.
O. Häusser,R. Abegg,R. G. Jeppesen,R. Sawafta,A. Celler,A. Green,R. L. Helmer,R. Henderson,K. Hicks,K. P. Jackson,J Mildenberger,C. A. Miller,Michel Vetterli,S. Yen,MJ Iqbal,R. D. Smith +15 more
TL;DR: Comparison of the results with relativistic and nonrelativistic impulse-approximation models shows that Fermi-motion averaging, a realistic nuclear response function, and medium modifications of the NN interaction are essential ingredients of a successful theory.

Spin observables for 208Pb(→p, →p) elastic scattering at 290 MeV
O. Häusser,K.H. Hicks,C.W. Glober,R. Abegg,A. Celler,C. Gunther,R. L. Helmer,Robert Henderson,D. J. Horen,C.J. Horowitz,K. P. Jackson,J. Lisantti,D.K. McDaniels,C. A. Miller,R. Sawafta,L.W. Swenson +15 more
TL;DR: In this paper, a newly constructed focal plane polarimeter for the medium resolution spectrometer at TRIUMF was used to measure polarizations and polarization transfer coefficients for protons elastically scattered from 208Pb at 290 MeV.

Spin-dependent observables for the 12C(p,p' gamma ) reaction at 400 MeV.
K. Hicks,R. Abegg,A. Celler,O. Häusser,R.S. Henderson,N. W. Hill,K. P. Jackson,R. G. Jeppesen,Nicholas S. P. King,M. A. Kovash,R. P. Liljestrand,C. A. Miller,George L. Morgan,J.R. Shepard,A. Trudel,Michel Vetterli,S. Yen +16 more
TL;DR: Coincident cross sections for rays emitted normal to the reaction plane and angular correlations for ..gamma.. rays emitted in the proton scattering plane are presented and compared with predictions from both nonrelativistic and relativistic models of proton-nucleus scattering calculated in the impulse approximation.
