Angular and energy dependences of emission probability for light particles in 22Ne-induced reactions at 8 MeV/nucleon

Influence of projectile cluster properties on fragment emission in incomplete-fusion reactions

“…4 the numerical results of Eq. (14) are compared with the experimental values of the differential cross-section at the energy E2 p for different fragments emitted in the reaction 22Ne + 181Ta [ 19] at energy ENe --= 178 MeV. Both the relative charge and mass dependence of the crosssection values are reproduced well except for the case of 4He.…”

“…In Fig. 3 the calculated widths for 4He from different projectiles are presented and compared with some values obtained by fits to high-energy part of inclusive spectral [6,19,21,22]. One can see from Fig.…”

“…4. The experimental differential cross-section for different fragments emitted in the 22Ne (178 MeV)+ la~Ta reaction [19] at the fragment energy E~ p (full circles). The numerical results (open circles connected with lines to guide the eye) are normalized to the data of the He fragments tive distance of the fragments associated with the projectile cluster state, are decisive for the parallel width of the fragment spectrum.…”

“…3 that Eq. (13) (13)) of 4He fragments originating from different projectiles are compared with the widths obtained by fit to high-energy part of the experimental inclusive spectra of 14N [22], 160 [21], 2~ [6] and 22Ne [19] Fig. 4.…”

“…The experimental data for 2~ projectile are taken from [71 whereas the width values for 22Ne case are extracted directly from the experimental spectra of Ref. [19] by fit to reproduce the high-energy part of the inclusive spectra. The fit is performed with respect to the fragment linear momentum k~ = ke mUme corresponding to the projectile velocity at the top of the Coulomb barrier in the entrance channel 9 The factor #~ k, is also taken into account 9 As can be seen from Fig.…”
