摘要：
We investigate the possibility of producing hypernuclei with proton beams via (p,K+) reaction. We present differential cross sections calculations utilizing the distorted wave impulse approximation in momentum space. We consider the reactions C-12(p,K+)(Lambda)C-13 and O-16(p,K+)(Lambda)O-17 within the energy region 0.8 GeV-1.2 GeV. We study both the case of formation of Lambda in S-state (C-12) and P-state (O-16). We take into account the contribution of both one-step and two-step processes when Lambda K pair is produced directly by incoming proton and intermediate pion, respectively. It is found that practically in all cases the two-step processes give significant contribution.
