DETERMINATION OF THE PHASE FOR NUCLEON-NUCLEON SCATTERING BY HULTHEN''S VARIATIONAL METHOD
应用忽鲁登变分法决定核子与核子散射的周相

A variational method for the determination of the phase,originally devcloped by Hulthén is appledhere to a two nuclecon system,the nuclcar potential being taken as a superposition of Yukawa potentialsof different ranges.Hulthén's method is also gencralized to include a Coulomb potential when necessary,Formulac are obtained in the form of power series which are useful for encrgies less that 40 Mev.
