摘要：

We discuss spin asymmetry of the ground states for the trapped spin-degenerate (two components) gases of fermionic atoms with a repulsive interaction between different spin components. The asymmetric state in different spin components, "collective ferromagnetic state", is shown to appear as the ground state in the system with a strong repulsive interaction or with large particle numbers. A condition for the asymmetric ground state to occur is obtained. (C) 2003 Elsevier Science B.V. All rights reserved.
