The quantum fluctuations of the two-phase Skyrme soliton model of the nucleon is formulated. The p-wave πN phase shift and the Roper to πN decay width are calculated as a function of the equlibrium defect radius R0. It is found that there is a preferred region of R0 between 0.4 and 0.5 fm where the experimental width can be fitted. It is also found that the region of R0 between 0.1 and 0.36 fm should be excluded in the model due to its instability against small oscillations.
