1. The problem statement, all variables and given/known data Consider the production of the K+ in the reaction: [tex]\gamma[/tex] p --> Κ+ Λ – What will be the minimal [tex]\gamma[/tex] energy if the proton is not free but is bound in the nucleus? Take into account the Fermi motion with p=250 MeV/c. 2. Relevant equations proton mass = 770 MeV Kaon mass = 494 MeV hyperon mass = 1100 MeV 3. The attempt at a solution I cant find anywhere in my book explaining what fermi motion is. The binding energy depends on how big the nucleus is, which isnt specified unless fermi motion does so.
