Nuclear multifragmentation time-scale and fluctuations of largest fragment size

D. Gruyer, J. D. Frankland, R. Botet +18

Distributions of the largest fragment charge, Zmax, in multifragmentation reactions around the Fermi energy can be decomposed into a sum of a Gaussian and a Gumbel distribution, wh…

Preparation and characterisation of isotopically enriched TaO targets for nuclear astrophysics studies

A. Caciolli, D. A. Scott, A. Di Leva +33

The direct measurement of reaction cross sections at astrophysical energies often requires the use of solid targets of known thickness, isotopic composition, and stoichiometry that…

New isospin e ffects in central heavy-ion collisions at Fermi energies

F. Gagnon-Moisan, E. Galichet, M. -F. Rivet +20

Isospin e ffects on multifragmentation properties were studied thanks to nuclear collisions between di fferent isotopes of xenon beams and tin targets. It is shown that, in central…
