摘 要：to extract physical properties of nuclei in the skyrme model, a semi-classical approach is taken involving studying quantum mechanics on a suitable finite-dimensional configuration space. this is necessary due to the mathematical complexity of the model, and over the years many different approaches have arisen which each have their own advantages and disadvantages. in recent years, several sophisticated tools have been developed in the context of one of these approaches - the instanton approximation - which amongst all approximations allows the most diverse range of configurations to be studied. in this talk we shall review this recent progress, and illustrate in detail how these tools may be applied explicitly via an example: a quantization of the 8-skyrmion, which models the beryllium-8 nucleus.
