Deuteron elastic scattering at 110 and 120 MeV.
We have measured deuteron elastic scattering cross sections at 110 MeV on C and Pb, and at 120 MeV on C and Ni, with the Texas ARM K500 cyclotron. The motivation for this experiment is that, except for some limited data above 200 MeV [1], there exists no elastic scattering data above 90 MeV. In order to calculate deuteron optical potentials in the energy range accessible by the K500 cyclotron, ...
متن کامل57%o REACTIONS AT EP = 120 MeV
Differential cross sections for the (p, n) reaction on ‘*,%r and 57,5XFe have been measured for angles up to Slirh = X0.5” and 14.6”, respectively, using 120 MeV protons. The observed angular distributions are used to evaluate the location and strength of Gamow-Teller resonances. A shell-model calculation of this strength distribution is presented and compared with the experimental results. The...
متن کاملC harge - exchange scattering in K - p interactions below 300 MeV
Cross sections for K p charge exchange, based on new data equal in statistics to the sum of those of all previous determinations below 300 MeV/c, are presented. The results confirm an earlier observation by this collaboration that the previous measurements of these cross sections at low momentum were significantly underestimated. Evidence for the presence of P wave scattering is presented.
متن کاملComment on “ πNN Coupling from High Precision np Charge Exchange at 162 MeV ”
In this updated and expanded version of our delayed Comment we show that the np backward cross section, as presented by the Uppsala group[1], is seriously flawed (more than 25 sd.). The main reason is the incorrect normalization of the data. We also show that their extrapolation method, used to determine the charged πNN coupling constant, is a factor of about 10 less accurate than claimed by Er...
متن کاملDifferential cross sections for pion charge exchange on the proton at 27 . 5 MeV
We have measured pion single charge exchange differential cross sections on the proton at 27.5 MeV incident π kinetic energy in the center of momentum angular range between 0 and 55. The extracted cross sections are compared with predictions of the standard pion-nucleon partial wave analysis and found to be in excellent agreement. Typeset using REVTEX
