 53CU c  2013Bl04: {+53}Cu described as proton unbound nucleus from an analysis 
 53CU2c  of results of their experiment carried out at GANIL and reported in    
 53CU3c  2005Bl15. Based on this analysis, S(p) and upper limit of half-life    
 53CU4c  are deduced                                                            
 53CU c  In previous Nuclear Data Sheets evaluation (2009Hu15) and NUBASE-2012  
 53CU2c  (2012Au07), {+53}Cu is listed as identified based on a statement in    
 53CU3c  1994BlZW "in another measurement, the isotopes {+53},{+54}Cu and       
 53CU4c  {+49}Co have been found to be unbound". However, in a follow-up        
 53CU5c  1994Bl10 publication, authors did not discuss this nuclide. On enquiry 
 53CU6c  by one of the current evaluators, 2013Bl04 stated that nothing could   
 53CU7c  be said about the {+53}Cu nuclide in their 1994Bl10 paper. Instead,    
 53CU8c  2013Bl04 reanalyzed their 2005Bl15 experiment to set a limit on        
 53CU9c  half-life and cross section, and published 2013Bl04 paper.

 53CU2cL production |s=1|*10{+-10} b in Ni({+58}Ni,X),E=74.5 MeV/nucleon, which 
 53CU3cL is consistent with non-observation of events related to {+53}Cu        
 53CU4cL nuclide. If this nuclide were bound, 2013Bl04 estimate that about 1250 
 53CU5cL events should have been detected in the above reaction.
