Spin dipole excitations in radiative pion capture on 1p shell nuclei

Dipole excitations inp-shell nuclei via (p,n) reactions

“…The results are presented in Figs. 5 As shown in these figures (5 -10) the cross section for AL= 1 transitions is clearly affected by QF subtraction and the quantitative evaluation of this effect is discussed in Sec. IV C. It is also shown in these MD-analyzed spectra that transitions characterized with EL=2 are almost completely missing in the corresponding QF subtracted spectra.…”

“…11 a summary of the 0&, b= 10' differential cross sections for the AL=1 transitions obtained in MD analysis with subtracted QF contributions. In each case, the spectra are compared with (y, n) spectra on the same target that have been shifted according to the reaction Q [5,50]. Recently, Sakuta et al [9]reported that three resonances around E = 6, 12, and 20 MeV are observed in He from the 6Li(7Li, 7Be)6He reaction at a beam energy of 82 MeV [9].…”

Gamma rays from muon capture in 14N

“…Also given are the integrated yields for the (γ,p) reaction up to 29 MeV [49,50], the (π − ,γ) yields of Perroud et al [15], the (µ − ,ν) calculation of Kissener et al [21] (all transitions), the calculation of Mukhopadhyay [11] (allowed transitions only, i.e. 1 + ), and the (π − ,γ) calculation of Kissener et al [18] (all transitions). [Note unbound energies do not always agree!…”

“…As their resolution was only 720 keV all the bound levels are in one unresolved peak with a yield of 6.2(4)% of all radiative capture. We also give the calculated yields of Kissener et al [18] for the (π − ,γ) reaction. These values have been estimated from the height of the bars in a figure, so are approximate .…”
