The purpose of the workshop is to assemble an audience which will discuss, from first principles, recent developments of the physics of fission. This shall serve to clarify current key problems such as the mechanism of the interplay between the single-particle and collective motion with large amplitude, timescale, dissipation and pre-fission configuration in nuclear fission- and fusion-fission reaction, settle modern trends in cluster fission.


Along with well-established ideas, it will in particular contemplate less conventional areas such as prompt fission in muonic atoms and lambda hypernuclei, and ternary fission into comparable fragments, which provide very critical tests of methods and ideas.

Atomic Fission:

1. Survey of the experimental situation.

2. Theoretical Approaches:
a. Cluster Dynamics;
b. Resonance Dynamics;
c. Fission Barrier;
d. Effective Potential;
e. Barrier from a density functional approach;
f. Exotic Cluster Emission;
g. Cluster Decay.

Nuclear Fission:

1. Survey of data on spontaneous, isomer, cold, and particle induced fission.
2. Theoretical Approaches:
a. Liquid drop approach;
b. Time-dependent approach;
c. Energy-density functional approach;
d. Barrier Penetration Problem;
e. Theory of Induced Fission;
f. Fusion-fission and superheavies


Participation is by invitation and limited to approximately 50. Those interested in attending should return the attached form by January 15, 2000, indicating a proposed topic or title. Those who have already confirmed their participation are kindly asked to reconfirm. Qualified applicants, irrespective of nationality, will be eligible for consideration as participants of FDACN.


The Workshop will take place at Luso, a fashionable spa located in a touristic region about 200 km North of Lisbon. Participants will be housed in the modern Grande Hotel das Termas do Luso.
