Time scales for fission at finite temperature
H. Hofmann, F. A. Ivanyuk
The concept of the "transient effect" is examined in respect of a "mean first passage time". It is demonstrated that the time the fissioning system stays inside the barrier is much…
Nuclear fission: The "onset of dissipation" from a microscopic point of view
H. Hofmann, F. A. Ivanyuk, C. Rummel +1
Semi-analytical expressions are suggested for the temperature dependence of those combinations of transport coefficients which govern the fission process. This is based on experien…
Pairing and shell effects in the transport coefficients of collective motion
F. A. Ivanyuk, H. Hofmann
The linear response approach to nuclear transport has been extended to pair correlations. The latter are treated within a mean field approximation to a pairing interaction with con…
Warm nuclei: The transition from independent particle motion to collisional dominance
H. Hofmann, Fedor A. Ivanyuk, Alexander G. Magner
We study large scale collective dynamics of isoscalar type and examine the influence of interactions residual to independent particle motion. It is argued that for excitations whic…
On the nature of nuclear dissipation, as a hallmark for collective dynamics at finite excitation
Helmut Hofmann, Fedor A. Ivanyuk, Shuhei Yamaji
We study slow collective motion of isoscalar type at finite excitation. The collective variable is parameterized as a shape degree of freedom and the mean field is approximated by…
