We study oscillons in D+1 space-time dimensions using a spherically symmetricansatz. From Gaussian initial conditions, these evolve by emitting radiation,approaching ``quasi-breathers'', near-periodic solutions to the equations ofmotion. Using a truncated mode expansion, we numerically determine thesequasi-breather solutions in 25 and the possibility of stable solutions for D<2.Comment: 18 pages and 18 figure
