 73SR c  {+73}Sr nuclei were produced at the RIBF-RIKEN facility                
 73SR2c  in the {+9}Be({+124}Xe,X) reaction at E=345 MeV/nucleon.               
 73SR3c  Fragments were separated in the first stage of BigRIPS                 
 73SR4c  and then identified by measuring |DE, tof and B|r using BigRIPS        
 73SR5c  and the zero-degree spectrometer. Reaction products were implanted     
 73SR6c  into the beta-counting system WAS3ABi, consisting of a double-sided    
 73SR7c  silicon-strip detector. Measured implanted ion-|b{++}-t; deduced

 73SR c  2020Ho06: {+73}Sr nuclei were produced in the fragmentation of {+92}Mo 
 73SR2c  beam at 140 MeV/nucleon on 152.2 mg/cm{+2} thick {+9}Be target,        
 73SR3c  followed by separation of fragments using A1900 Fragment separator and 
 73SR4c  further purification of {+73}Sr secondary beam by Radio Frequency      
 73SR5c  Fragment Separator (RFFS) at NSCL-MSU facility. Nuclei of interest     
 73SR6c  were implanted into a 520-|mm double-sided silicon strip detector      
 73SR7c  (DSSSD) detector for the detection of correlated implants              
 73SR8c  and decay events. Measured implant-decay correlations, E(p), I(p),     
 73SR9c  E|g, I|g, half-life of {+73}Sr decay, and branching ratios. Deduced    
 73SRAc  energy and J|p of the isobaric analog state (IAS) in {+73}Rb,          
 73SRBc  levels in {+72}Kr from |b{++}-delayed proton decay, and J|p of the     
 73SRCc  ground state of {+73}Sr. Discussed breakdown of mirror symmetry        
 73SRDc  between the ground states of mirror nuclei: {+73}Sr and {+73}Br.       
 73SREc  Analysis of modeling of the decay pattern was done using Gamow         
 73SRFc  coupled-channel (GCC) approach.

 73SR2cL S(2p)({+73}Sr)=200 {I420} (syst, 2017Wa10), two-proton decay mode to   
 73SR3cL {+71}Kr cannot be ruled out. Note that S(p)({+73}Sr)=910 {I640}        
 73SR4cL (syst, 2017Wa10), which makes one-proton decay mode almost forbidden.  
 73SR cL E$2020Ho06 mention that the observation of ions decaying only with     
 73SR2cL one half-life suggests that these events correspond to the ground-state
 73SR3cL of {+73}Sr.                                                            
 73SR cL J$assigned by 2020Ho06, based on (5/2-) for {+73}Rb IAS, deduced from  
 73SR2cL comparison of measured proton branching ratios from {+73}Rb IAS to the 
 73SR3cL g.s. and the first 2+ state of {+72}Kr, and the predicted values from  
 73SR4cL the GCC calculations, with oblate deformation for the {+72}Kr core.    
 73SR5cL With the g.s. J|p=1/2- for the g.s. of {+73}Br, mirror nucleus of      
 73SR6cL {+73}Sr, 2020Ho06 discussed the violation of mirror-symmetry breaking  
 73SR7cL in the case of the two mirror nuclides. Note that 26.9-keV, (5/2-)     
 73SR8cL level in {+73}Br is the likely the analog of {+73}Sr g.s., thus        
 73SR9cL reversing the order of the ground and the first excited states in the  
 73SRAcL two mirror nuclei.

 73SR2cL and their subsequent decays, by rejected the latter if another         
 73SR3cL implantation event occurred within 10 half-lives of {+73}Sr. The       
 73SR4cL analysis was done using logarithmic-binning method for low statistics. 
 73SR5cL Other: 23.5 ms {I18} from direct fitting of the data (2020Ho06).       
 73SR6cL The half-life from 2020Ho06 can be compared with 24.3 ms {I53} and     
 73SR7cL 28 ms {I+5-4} measured by 2019Si33 (Phys. Rev. C 100, 044311), the     
 73SR8cL first value from least-squares fit to ({+73}Sr implants)|b decay curve,
 73SR9cL and the second value from logarithmic binning method for 42 observed   
 73SRAcL (implants)|b events. Weighted average of all the four values, deduced  
 73SRBcL by compiler, is 23.6 ms {I14}, whereas weighted average of the two     
 73SRCcL values obtained from the logarithmic binning method is 23.6 ms {I15}.  
 73SR cL $Two strong proton peaks are observed from beta-delayed proton decay:  
 73SR2cL {+73}Sr |) {+73}Rb |) {+72}Kr. The most intense peak was               
 73SR3cL E(p)=3.80 MeV {I2}, identified as emanating from {+73}Rb               
 73SR4cL isobaric-analog state (IAS) to feed the ground state of {+72}Kr.       
 73SR5cL From observation of ten (709.7|g)p-coin events, the second strong peak 
 73SR6cL was attributed to the branching of {+73}Rb, IAS decays to the first    
 73SR7cL 2+ state in {+72}Kr.
