The Woods-Saxon ∧-nucleus potential and the phenomenological estimate of the ∧-well depth

Summary

∧ Woods-Saxon ∧-nucleus potential is considered and an attempt is made for the determination of the ∧ well depth and other parameters by leastsquare fitting to experimental binding energies (B _∧) of the ∧ in hypernuclei. The expression for the half-way radius of the well employed is more complicated than the standard onec =r ₀∧^3/1. The Walecka-type « semi-empirical mass formula » forB _∧, derived by Deloff, is also discussed.
