PROTONS AND ALPHA PARTICLES EMITTED FROM FISSION INDUCED BY 720MeV 12C ON 232Th

  • Triple differential cross sections for p and α particles in fission induced by 720MeV 12C on 232Th are presented. The experimental results comfirm that p and α particles are emitted prior to fission, while the low energy components of p and α-spectra are attributed to quasi-thermal evaporation of targetlike residues. p and α-spectra are fitted with moving source model. α-spectra are well reproduced with coalescence model.

PROTONS AND ALPHA PARTICLES EMITTED FROM FISSION INDUCED BY 720MeV 12C ON 232Th

    Corresponding author: SONG Shi-Zhan,

Abstract: Triple differential cross sections for p and α particles in fission induced by 720MeV 12C on 232Th are presented. The experimental results comfirm that p and α particles are emitted prior to fission, while the low energy components of p and α-spectra are attributed to quasi-thermal evaporation of targetlike residues. p and α-spectra are fitted with moving source model. α-spectra are well reproduced with coalescence model.
