Core polarization, Brown-Rho scaling and a memory of Gerry's Princeton years

摘要

Core-polarization (CP) and Brown-Rho (BR) scaling were among Gerry's mostfavorite topics. In this contribution, we will discuss some of the earlyhistory as well as more recent work associated with these two fascinatingphenomena. I (TTSK) will begin with some recollections of Princeton, where Imet Gerry for the first time in 1964 and worked as his postdoc. Corepolarization was in fact the first topic he assigned to me. JWH started workingwith Gerry at Stony Brook from 2003 and was Gerry's last student in nuclearphysics. We three had teamed up well, working closely on both CP and BRscaling, particularly on the latter's connection to the anomalously-longbeta-decay lifetime of carbon-14. We shall here briefly review these topics,including a recently developed new Brown-Rho scaling based on a Skyrmionhalf-Skyrmion two-phase model.
