COMPLEX FRAGMENT EMISSION FROM THE HE-3+AG-NAT SYSTEM BETWEEN 0.48 AND 3.6 GEV Academic Article uri icon

abstract

  • The emission of complex fragments (3Z12) from reactions of 3He with natAg has been studied at bombarding energies of E = 480, 900, 1800, 2700 and 3600 MeV. Between 900 and 1800 MeV slopes of the fragment kinetic energy spectra at backward angles undergo a change in character, becoming much flatter; in addition, the Coulomb peak is found to broaden significantly and shift to lower energies. Power-law fits to the fragment charge distributions result in decreasing values of the exponent up to a bombarding energy of 1800 MeV; at this value and beyond, a constant value of =2.10.1 is observed. Elemental cross sections at the highest energy are found to increase by approximately two orders of magnitude relative to data near 100 MeV. The data suggest a change in reaction mechanism between incident energies of 900 and 1800 MeV. 1990.
