Abstract

The low-lying excitation spectra from the yrast line of weakly interacting trapped bosons was reported. This spectra was caused due to the pairwise repulsive interaction between octupole modes. Low-lying quasidegenerate eigenenergies of weakly interacting trapped N bosons with total angular momentum "L" was determined for small L/N. There was no interaction between the quadrupole modes. The quadrupole modes exhaust the low-lying spectra that were separated from the others by energy gaps linear in N.
