Abstract : This paper is a short revisit to Kuo-Brown effective interaction derived from the Hamada-Johnston nucleon-nucleon potential, done
by Gerry Brown and Tom Kuo. This effective interaction, derived in year 1966, is the first attempt to describe nuclear structure
properties from the free nucleon-nucleon potential. Nowadays much progress has been achieved for the effective interactions in
shell model. We would compare the effective interactions obtained in the 1966 paper with up-to-date shell-model interactions in
sd-shell and pf-shell model space. Recent knowledge of effective interactions on nuclear structure, can also be traced in the Kuo-
Brown effective interaction, i.e., the universal roles of central and tensor forces, which reminds us that such discovery should be
noticed much earlier.
