General Comments:

1991Mo10: 62Ge first identified in fragmentation of 78Kr beam at 65 MeV/nucleon using A1200 spectrometer at NSCL, MSU. Isotopic identification by time-of-flight and energy loss methods

2002Lo13 (Also 2002Bl17): 62Ge observed in fragmentation of 78Kr beam at 73 MeV/nucleon using LISE3 spectrometer at GANIL facility. Isotopic identification by time-of-flight and energy loss methods. Measured isotopic half-life by decay timing of correlated β+ (ion implant) events and energy loss vs time-of-flight

2005St29 (also 2005St34): 62Ge observed in fragmentation of 78Kr beam at 140 MeV/nucleon with a Be target using A1900 spectrometer at NSCL, MSU. Measured cross section=4.8 nb 20

2007Bl09: 62Ge observed in fragmentation of 70Ge beam at 71.6 MeV/nucleon with a Ni target using LISE3 spectrometer at GANIL facility

Structure calculations:

1988Do08: calculated deformation energy vs quadrupole moment, Hartree-Fock method and Skyrme force

Q-value: Note: Current evaluation has used the following Q record

Q-value: ΔQ(β-)=329, ΔS(n)=330, ΔS(p)=ΔQ(α)=150 (syst,2011AuZZ,2003Au03)

Q-value: Q(εp)=6810 140 (syst,2011AuZZ,2003Au03). S(2n)=30776 240, S(2p)=2647 140 (syst,2011AuZZ). 2003Au03 list S(2n)=30620 270, S(2p)=2630 140 from syst

Additional Level Data and Comments:

E(level)Jπ(level)T1/2(level)Comments
   964   Jπ(level): In comparison to low-lying structures in 62Zn and 62Ga, the 964- and 2285-keV levels may be assigned 2+ and 4+, respectively. However as pointed out by 2005Ru06, much better statistics are needed to make definitive assignments.
  2285   Jπ(level): In comparison to low-lying structures in 62Zn and 62Ga, the 964- and 2285-keV levels may be assigned 2+ and 4+, respectively. However as pointed out by 2005Ru06, much better statistics are needed to make definitive assignments.
