摘要：

The results of a measurement of the cross section d3σ/dΩα1 dΩα2dE for the (α, 2α) reaction on 6Li, 10B, C, O, Na, Al, Fe, Cu and Pb, are presented. Values for the effective cluster number n0eff are deduced for these targets excluding lead, using the PWIA. It is observed that the PW1A value of neff is strongly dependent upon the theoretical shape assumed for the internal momentum distribution of the α-cluster. Using a S-state pole approximation for the momentum distribution leads to a value of the virtual decay amplitude g for A → α + (A - 4) which is the same from 6Li to Fe. © 1979.
