STELLAR ELECTRON-CAPTURE RATES: A COVARIANT DENSITY FUNCTIONAL CALCULATION

Gamow-Teller transitions and stellar electron-capture rates in hot nuclei are computed using the self-consistent finite-temperature relativistic random-phase approximation (FTRRPA). The predicted electron-capture rates in stellar environment for Fe-54,Fe-56 are consistent with those obtained in the shell-model approach. The FTRRPA provides an efficient and accurate theoretical framework for large-scale calculations of stellar electron-capture rates.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000338140500033&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701Physics, NuclearCPCI-S(ISTP)
