متن کاملREACTION AT 198 MeV
The reaction 45Sc(n, P)45Ca has been studied at an energy of 198 MeV with energy resolution of about 1 MeV. Measurements were carried out at nominal angles 0°, 3°, 6®, 9®, 12°, 15°, 18" and spectra obtained up to -40 MeV excitation energy in 45Ca . Significant Gamow-Teller strength is observed at an excitation energy of about 7 MeV, somewhat higher than predicted by shell-model calculations . T...
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 کاملNuclear spin-orbit interaction from chiral pion-nucleon dynamics
Using the two-loop approximation of chiral perturbation theory, we calculate the momentum and density dependent nuclear spin-orbit strength Uls(p, kf ). This quantity is derived from the spin-dependent part of the interaction energy Σspin = i 2 ~σ ·(~q×~p )Uls(p, kf ) of a nucleon scattering off weakly inhomogeneous isospin symmetric nuclear matter. We find that iterated 1π-exchange generates a...
متن کاملSPIN-FLIP ASYMMETRY IN THE PROTON INELASTIC SCATTERING TO THE FIRST 2+ STATES OF 48,50 Ti
Angular distributions of the differential cross section a(@), analyzing power Ay(8), spin-flip probability S(8) and spin-flip asymmetry e(6') in the excitation of the first 2+ states in 48Ti and 50Ti were measured at incident energies of 11 and 18 MeV using (p,ply) coincidence technique with polarized proton beam. The results were analyzed in terms of a macroscopic coupled channels method based...
