Cooling Dynamics in Multi-fragmentation processes
T. X. Liu, W. G. Lynch, M. J. van Goethem +20
Fragment energy spectra of neutron deficient isotopes are significantly more energetic than those of neutron rich isotopes of the same element. This trend is well beyond what can b…
Comparison of mid-velocity fragment formation with projectile-like decay
S. Hudan, R. Alfaro, B. Davin +17
The characteristics of intermediate mass fragments (IMFs: 3<=Z<=20) produced in mid-peripheral and central collisions are compared. We compare IMFs detected at mid-velocity with th…
Interplay of initial deformation and Coulomb proximity on nuclear decay
S. Hudan, R. Alfaro, L. Beaulieu +18
Alpha particles emitted from an excited projectile-like fragment (PLF*) formed in a peripheral collision of two intermediate-energy heavy ions exhibit a strong preference for emiss…
Isospin Diffusion in Heavy Ion Reactions
M. B. Tsang, T. X. Liu, L. Shi +18
Using symmetric 112Sn+112Sn, 124Sn+124Sn collisions as references, we probe isospin diffusion in peripheral asymmetric 112Sn+124Sn, 124Sn+112Sn systems at incident energy of E/A=50…
Coulomb proximity decay: A clock for measuring the particle emission time scale
S. Hudan, A. S. Botvina, R. Alfaro +19
A new method to examine the time scale of particle emission from hot nuclei is explored. Excited projectile-like and target-like fragments decay as they separate following a periph…
Excitation and decay of projectile-like fragments formed in dissipative peripheral collisions at intermediate energies
R. Yanez, S. Hudan, R. Alfaro +18
Projectile-like fragments (PLF:15<=Z<=46) formed in peripheral and mid-peripheral collisions of 114Cd projectiles with 92Mo nuclei at E/A=50 MeV have been detected at very forward…
Precise Barriers and Shell Effects: a New Inroad to Fission Saddle Point Spectroscopy
L. Phair, L. G. Moretto, K. X. Jing +6
Fission excitation functions have been measured for a chain of neighboring compound nuclei, from 207Po to 212Po. We present a new analysis which provides a determination of the fis…
Fragment Production in Non-central Collisions of Intermediate Energy Heavy Ions
B. Davin, R. Alfaro, H. Xu +19
The defining characteristics of fragment emission resulting from the non-central collision of 114Cd ions with 92Mo target nuclei at E/A = 50 MeV are presented. Charge correlations…
Isotope yields from central 112,124Sn+112,124Sn collisions, dynamical emission?
T. X. Liu, X. D. Liu, M. J. van Goethem +21
Isotopic yields for light particles and intermediate mass fragments have been measured for 112Sn+112Sn, 112Sn+124Sn, 124Sn+112Sn and 124Sn+124Sn central collisions at E/A=50 MeV an…
Similarity of fragment characteristics at mid-velocity for mid-peripheral and central collisions
S. Hudan, R. Alfaro, B. Davin +19
The characteristics, in particular the isotopic composition (N/Z), of intermediate mass fragments (IMF : 3<=Z<=20) produced near the center-of-mass in mid-peripheral and central co…
Origins of Intermediate Velocity Particle Production in Heavy Ion Reactions
L. Gingras, A. Chernomoretz, Y. Larochelle +10
Investigation of intermediate-velocity particle production is performed on entrance channel mass asymmetric collisions of 58Ni+C and 58Ni+Au at 34.5 MeV/nucleon. Distinctions betwe…
The liquid to vapor phase transition in excited nuclei
J. B. Elliott, L. G. Moretto, L. Phair +16
For many years it has been speculated that excited nuclei would undergo a liquid to vapor phase transition. For even longer, it has been known that clusterization in a vapor carrie…
A statistical interpretation of the correlation between intermediate mass fragment multiplicity and transverse energy
L. Phair, L. Beaulieu, L. G. Moretto +29
Multifragment emission following Xe+Au collisions at 30, 40, 50 and 60 AMeV has been studied with multidetector systems covering nearly 4-pi in solid angle. The correlations of bot…
Statistical Exploration of Fragmentation Phase Space Source Sizes in Nuclear Multifragmentation
L. G. Moretto, L. Beaulieu, L. Phair +1
The multiplicity distributions for individual fragment Z values in nuclear multifragmentation are binomial. The extracted maximum value of the multiplicity is found to depend on Z…
Multifragmentation at Intermediate Energy: Dynamics or Statistics?
L. Beaulieu, L. Phair, L. G. Moretto +1
To make a statement about the nature and mechanism of fragmentation, it is necessary to probe directly any competition, or lack thereof, between the emission of various particle sp…
