A Simple Analysis of theLi6(p, pd)He4

Quasi-Free Scattering

“…Thus the (P,2P) work performed and in progress (113 -116) at relatively low incident energies (",50 MeV or less) has certainly not had the space it deserves; however, in this energy region intri cate problems connected with diffraction and distortion are encountered which seem to be absent or at least unimportant above 150 MeV (100,101). N or have we surveyed the studies of quasi-free scattering effects on nucleon clusters such as high energy (p,pd) , (P,POl) , and (01,201) reactions which have been performed (30)(31)(32)(33)(34)(35)(36)(37)(38)(39)(40) and discussed (70, 117 -123) . For these reactions a correct treatment of the antisymmetrization requirement is important (119,120) and the strong absorption of the composite outgoing particle necessi tates a careful choice of the scattering geometry (121).…”

Quasifree Knockout of Deuterons in theLi6(α,αd)HeBähr1, Becker2, Bilaniuk3 et al. 1969Phys. Rev.20010View full textAdd to dashboardCite

“…This value is somewhat smaller than that obtained by Jain et al, lt7 but is in good agreement with the results of an analysis of earlier 6 Li(/>, pd) 4 He data. 8 To obtain the best fit to the angular correlation data of Fig. 3(b), again a value of EB=0.6 MeV had to be used.…”

“…The corresponding a-d knockout has been studied, 8 also in the principal plane, at 42.5 MeV. In the present experiment, the 6 Li(a, ad)*H.e reaction was investigated at E a = 23.6 MeV, in the principal plane and out of it, in order to test the validity of the 6 Li cluster model and to ascertain the applicability of the impulse approximation at the relatively low cm.…”

“…The shape of the peak due to the 2.9-MeV level of 8 Be, which appears in the spectrum of Fig. 3(a), was fitted using the Breit-Wigner expression.…”

“…These values are in close agreement with those obtained from the analysis of the 6 Li(^, pd) 4 B.e reaction. 8 When the actual value of the binding energy 2£s = 1.47 MeV was substituted in the calculations, the corresponding factors were 6.8 and 17.5%, respectively.…”
