11. Current status and perspectives of nucleon and alpha knockout reaction

Kazuki Yoshida (Japan Atomic Energy Agency)

Invited talk

The proton-induced $\alpha$ knockout reaction, ($p$,$p\alpha$), is a powerful probe of the $\alpha$ formation in the nucleus. The author and the collaborators have shown that a modern theoretical calculation of the $\alpha$ amplitude combined with the ($p$,$p\alpha$) reaction calculation by the distorted wave impulse approximation can quantitatively reproduce the existing experimental data...

3. Theoretical model of the (p,pd) reaction for understanding deuterons inside nuclei

Invited talk

In the experiment performed 40 years ago at the University of Maryland, it was reported that the cross section of the $^{16}$O($p,pd$)$^{14}$N reaction [1] is almost half that of the $^{16}$O($p,2p$)$^{15}$N reaction [2]. This result may indicate that the existence probability of the deuteron in $^{16}$O is surprisingly high and that there are $pn$ correlations including the deuteron...

1. Multiple mechanisms in proton-induced one nucleon removal from $^{14}$O at $\sim$100 MeV/nucleon

Invited talk

One nucleon removal reactions at intermediate energies has been a powerful tool for single-particle structure studies of exotic nuclei [1], but the reaction mechanism is not fully understood [2-5]. One debated phenomenon is the asymmetric parallel momentum distribution (PMD) of the residual nucleus occuring occasional in one nucleon removal induced from light ion-targets [4,6,7]. Recent...

9. Nucleon knockout reactions within the intranuclear cascade model INCL

Jose Luis Rodriguez Sanchez (University of Coruña)

02/08/2023, 14:25

Invited talk

The main features of the intranuclear cascade model INCL for describing single-nucleon and multi-nucleon knockout cross sections will be presented in this talk. For the interpretation of experimental data on knockout cross sections, this model is coupled to the deexcitation code ABLA, which calculates the particle separation energies from the atomic mass evalutation AME2020. The results...
