“…In the associated excitation energy (e d ) range, other studies Hanna et al 1974;Breuer et al 1975) have observed fractionated El and E2 strengths as we conjecture from our analyses. More finely spaced (in energy) data and complementary measurements of polarizations would be most useful in furthering these analyses.…”

“…The width of that resonance may be assumed to be of the order of 5 MeV. As mentioned in the introduction, a similar concentration of E2 strength has been reported for the ~SN(p, ~,)t60 reaction with, however, a much smaller total strength [12].…”

“…In the reaction 15N(p, )')160, Hanna et al [12] found indications of a broad E2 resonance localized at an excitation energy slightly above that of the GDR. It was interpreted to be mainly isovector in character, exhausting approximately 30% of the isovector sum rule.…”

Radiative capture of polarized neutrons by 12C was investigated using a scintillating NE-213 target and three NaI detectors. Angular distributions of the capture gamma photons and analyzing powers were measured at laboratory angles of 55 ~ , 90 ~ and 125 ~ and neutron energies E,=20 to 35 MeV. Capture photons and recoil nuclei were detected in coincidence, the photons being identified by measuring the time of flight and analyzing the pulse shape in the NaI detectors. In the energy range above the centre of the GDR in 13C, a pronounced rise of the forward-backward asymmetry for the 12C(n, 7o) 13C reaction was observed indicating the presence of E2 capture interfering with direct and collective E1 capture. The direct-semidirect (DSD) model of radiative capture does not give a satisfactory description of the experimental results. 24.30.; 25.40. PACS:

“…The points were chosen so that the background joined the high-lying continuum smoothly down to the (x-particle threshold region, passing by the minima between the peaks in the 10 to 20 MeV excitation energy region. The results obtained are illustrated on figure 1. After subtraction of the background, the difference spectra have been unfolded into single peaks using a computer code performing a X2 search in each region of the spectrum and fitting at most 4 three-parameters gaussianshaped peaks.…”
