127PD c  2019Wa14: {+127}Pd isotopes were produced from in-flight of fission of 
127PD2c  {+238}U beam of 345 MeV/nucleon with 7-12 pnA intensity on a Be target 
127PD3c  at the I|g-Beam Factory (RIBF) in the RIKEN Nishina Center. Fission    
127PD4c  products were transported through the BigRIPS-ZeroDegree spectrometer  
127PD5c  and implanted into the WAS3ABi active stopper consisting of eight      
127PD6c  layers of double-sided silicon-strip detectors (DSSSDs) and |g rays    
127PD7c  were detected using the EURCA |g-ray spectrometer consisting of 12     
127PD8c  Cluster-type detectors, each of which contains 7 HPGe crystals packed  
127PD9c  closely. Measured E|g, I|g, |g(t). Deduced levels, spin-parities,      
127PDAc  half-life. Results are compared to the shell-model calculation,        
127PDBc  suggesting the competition between proton and neutron excitations in   
127PDCc  the proton-hole and neutron-hole systems in the south-west quadrant of 
127PDDc  the doubly magic nucleus {+132}Sn.

127PD2c  beam of 345 MeV/nucleon from the cascade operation of the RBIF         
127PD3c  complex of accelerators at RIKEN. Identification of {+127}Pd made on   
127PD4c  the basis of magnetic rigidity, time-of-flight and energy loss using   
127PD5c  the BigRIPS separator and ZeroDegree spectrometer. The separated nuclei
127PD6c  were sent to the Advanced Implantation Detector Array (AIDA) for the   
127PD7c  detection of implanted ions and subsequent |b{+-} and |b{+-}-delayed   
127PD8c  neutrons using six double-sided silicon-strip detector (DSSDs) for     
127PD9c  particles, and BRIKEN neutron counter array of 140 {+3}He proportional 
127PDAc  counters embedded in a high-density polyethylene (HDPE) matrix.        
127PDBc  Measured and analyzed (implanted ions)-|b, (implanted ions)-|b-n       
127PDCc  and (implanted ions)-|b-2n correlated events to deduce half-life of    
127PDDc  decay and delayed-neutron emission probability (%|b{+-}n or (P{-1n}).  
127PDEc  In the analysis, Bateman equation was used to fit the decay curve for  
127PDFc  the isotope of interest, subsequent daughters and grand-daughters in   
127PDGc  the decay chain to reach the final stable isotope. For details of the
