Transfer induced fission probabilities Pf have been measured in the collisions of 340 MeV 28Si on 232Th target as a function of the detected projectile-like fragment (PLF) charge. The measured Pf shows an increase with the net charge transfer ΔZ, in the range ΔZ =0-4. For larger ΔZ values (ΔZ =5-10), the fission probability exhibits first a saturation in the range of values Pf =0.4-0.6 and than a drop. Coincidences between PLF and light charge particles reveal that the charged particle emission is strongly damped when the fission fragments is required. An important component in the charged particle emission is localized in the direction of the recoiling target-like fragment (TLF); which is, in some cases, directly detected. Therefore results indicate a significant survival against fission of the populated TLF fragments.

Abstract
Transfer induced fission probabilities Pf have been measured in the collisions of 340 MeV 28Si on 232Th target as a function of the detected projectile-like fragment (PLF) charge. The measured Pf shows an increase with the net charge transfer ΔZ, in the range ΔZ =0-4. For larger ΔZ values (ΔZ =5-10), the fission probability exhibits first a saturation in the range of values Pf =0.4-0.6 and than a drop. Coincidences between PLF and light charge particles reveal that the charged particle emission is strongly damped when the fission fragments is required. An important component in the charged particle emission is localized in the direction of the recoiling target-like fragment (TLF); which is, in some cases, directly detected. Therefore results indicate a significant survival against fission of the populated TLF fragments.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
