β decay of deformed r-process nuclei near A=80 and A=160, including odd-A and odd-odd nuclei, with the Skyrme finite-amplitude method

RADIOACTIVITY ^{68,69,70,71,72}Cr, ^{71,72,73,74,75}Mn, ^{72,73,74,75,76}Fe, ^76,77Co, ^80,81Cu, ^84,85,86Zn, ^86,87Ga, ^{86,87,88,89,90,91,92}Ge, ^{89,90,91,92,93,94,95}As, ^{92,93,94,95,96,97,98}Se, ^{157,159,161,163,165,167}Cs, ^{163,165,167,169,171,173,175}La, ^{146,148,150,152,160,164,166,168,170,172,174,176}Ce, ^{152,154,156,164,166,172,174,176,178}Nd(β^-); calculated half-lives using proton-neutron finite-amplitude method (pn-FAM) with Skyrme energy-density functionals (EDFs) in the quasiparticle random-phase approximation (QRPA), after optimizing the nuclear interaction to best fit the measured half-lives in A=80 and A=160 regions. Deduced r-process abundances. Comparison with other theoretical calculations and experimental values.
