Abstract
Recent experiments at the CELSIUS storage ring of Uppsala, Sweden, have revealed the existence of high momentum transfer target-like fragments contrary to expectations. Recoiling heavy fragments in the reaction of 250 MCV/nucleon N-14 on Xe-131 have been measured at 10degrees with respect to the beam direction with specially designed recoil telescopes, Simulations with the Boltzmann-Uehling-Uhlenbeck (BUU) transport equation are not able to reproduce the experimental observations, Intermediate mass fragments (IMF: 3 less than or equal to Z less than or equal to 8) were also measured using three elements of the CIRCSi DeltaE - E telescopes. Single energy spectra of IMFs suggest that the larger fragments (Z = 7, 8) are preferentially emitted... (More)
