Our results indicate that fragmentation does not take place for values of the coupling for which the system is metastable. We also comment on the possibility of realizing a fragmented condensate in trapping potentials other than an harmonic one.5 pages, 2 figures, uses RevTeXStatistical Mechanicstext
