The FOPI Collaboration at the GSI SIS-18 synchrotron measured charged kaons from central and semicentral collisions of Ni+Ni at a beam energy of 1.91A GeV. We present the distribution of the K−/K+ ratio on the energy vs polar angle plane in the nuc

Pionska fuzija lakih jezgara

Autor: Gašparić, Igor, Čaplar, Roman, Joulaeizadeh, Leila, Löhner, Herbert

Reakcija pionske fuzije u kojoj se dvije jezgre fuzioniraju u novu emitirajući pritom pion, zahtijeva veoma koherentni mehanizam i stoga pruža uvid u kolektivno gibanje nukleona u jezgri. Reakcija 4He(3He, π0)7Be se eksperimentalno proučavala na
