Excited oscillons: Cascading levels and higher multipoles

We investigate two types of excited oscillons. first focus on spherical symmetry and find that there are a tower oscillons with higher energies. Despite having multiple approximate ``nodes'' in their energy density profiles, these long-lived. during the lifetime an oscillon it will cascade down all lower levels before its disintegration, each level-dropping period accompanied by short burst energy. also point out existence multipoles, which generally have shorter lifespans than ones. Apart from performing nonlinear simulations absorbing boundary conditions, we apply perturbative method to analyze some features
