Deuteron as a Soliton in the Skyrme Model

摘要

The minimal-energy static soliton solution with baryon number 2 in the Skyrme model is discussed. It is shown that, upon quantizing the spin isospin collective coordinates and taking into account a conjectured discrete symmetry of the solution, the lowest energy state can have the spin, isospin, and parity quantum numbers of the deuteron. This identification is supported by approximate calculations using a product ansatz, which give reasonable values for the charge radius and the magnetic and quadrupole moments.
