“…The magnitude of the peak is only about one-quarter of the measured cross section, however. Thus it is seen that overall agreement between the data and model predictions is poor, in marked contrast to results obtained in the study [9] of the ' N(n, p) reaction. This represents a serious failure of the calculations, but the reasons for the disagreement are not clear.…”

Cross sections for the He(n, p) reaction were measured at angles of 2.7 ', 7.5', 14.4', 28.2', and 34. 9' (c.m. ) at an incident beam energy of 288 MeV. Outgoing protons were observed to energies corresponding to a Q value of -40 MeV. The reduced cross section for the Gamow-Teller component of the ground-state isobaric-analog transition was determined to be & =o(q =0)/BGT =6.9+0.2 mb jsr. This value is significantly smaller than that observed for nuclei in the mass range 6~A~1 3. A multipole analysis of the data indicates that the cross section of the continuum up to a g value of -20 MeV involves mainly hL =1 spin dipole transitions. The analysis determines an upper limit of 0.06 units of Gamow-Teller strength in transitions to excited states between 7 and 16 MeV, but is consistent with no Gamow-Teller strength in this region. Distorted wave impulse approximation calculations using transition amplitudes from a large-scale shell model calculation provide a good fit to the measured groundstate cross section, but fail to account for the magnitude of the measured cross sections to the continuum below 30 MeV excitation.PACS number(s): 24.50.+ g, 25.40.Kv, 27.10.+h

Using the neutron time-of-flight facility at the Indiana University Cyclotron Facility we have studied (p, n) reactions on the light nuclei Li, ' "B,and ' ' C. Double differential cross sections have been measured between Hi, b=0' and 50' in 5' intervals, at E"=186MeV. Contributions of the quasifree reaction in the giant resonance region are estimated. Energy spectra of EL=1 transitions have been extracted using multipole decomposition analysis. The resulting EL=1 spectra are compared with results of photonuclear reactions.Empirical results are also compared with distorted wave impulse approximation calculations. PACS number(s): 25.40.Ep, 27.20.+n, 24.70.+s
