Angular Momentum Population in Projectile Fragmentation

Abstract. Isomeric states in neutron-deficient nuclei around A≈190 have been identified following the projectile fragmentation of a relativistic energy 238U beam. The deduced isomeric ratios are compared with a model based on the abrasion-ablation description. The experimental isomeric ratios are lower by a factor of ≈2 than the calculated ones assuming the ‘sharp cutoff’ approximation. The obs...

Temperature and Scaling studies from Projectile

Temperature and Scaling studies from Projectile Fragmentation of Kr+Ni at 35 MeV/A. (August 2009) Sara Katherine Wuenschel, B.S., LeTourneau University Chair of Advisory Committee: Dr. Sherry J. Yennello Many observables have been developed to study the effects of the two component nature of nuclei. This thesis has experimentally probed caloric curves as well as scaling observables for their de...

Collisions between 48 Ti 1 93 Nb at 917 MeV

One of the most striking findings in the early days of low-energy, heavy-ion nuclear physics was the observation of deep inelastic collisions ~DIC! @1#. These reactions can make up a substantial fraction of the total reaction cross section and are characterized by the conversion of a large amount of the relative kinetic energy into internal excitations of the colliding nuclei without obliterati...

Momentum distribution of fragments in heavy-ion reactions: Dependence on the stochastic collision process.

Momentum distribution of fragments produced in 12C+ 12C reaction at 28.7 MeV/nucleon is analyzed with antisymmetrized version of molecular dynamics (AMD). Calculations are made for several cases of stochastic collisions and the projectile fragmentation peak in momentum distribution is reproduced by the incorporation of many-body nature in stochastic collision process. Furthermore the value of t...

Investigation of the nuclear mean field by precision measurements of the spectator response to the participants blast

The longitudinal re-acceleration phenomenon of the fragmentation residues, as found recently in projectile fragmentation of uranium [1,2], has been interpreted [3] as the postulated spectator response to the participants’ blast [4]. According to transport calculations, the longitudinal momenta of the surviving residues yield a direct access to the momentum-dependent properties of the nuclear me...
