摘要
The OBELIX spectrometer, studying at the Low Energy Antiproton Ring (LEAR) of CERN the <(N)over bar N> annihilation, has collected annihilation data with very low momentum (p) over tilde (approximate to 50MeV/c). The results of the spin-parity analysis on the <(p)over bar p> annihilation into four and five pions are briefly described.
