Parallel Momentum Distribution of 28Si Fragments from 29P
-
Abstract
Distribution of the parallel momentum of 28Si fragments from the breakup of 30.7MeV/nucleon 29P has been measured on C targets. The distribution has the FWHM with the value of 110.5±23.5MeV/c, which is quantitatively consistent with the Galuber model calculation assuming by a valence proton in 29P. The density distribution is also predicted by the Skyrme--Hartree--Fock calculation. The results show that the proton-skin structure may exist in 29P.
