Q(β-)=4591 keV 5S(n)= 5990 keV 7S(p)= 7871 keV 5Q(α)= -3598 keV 8
Reference: 2017WA10

References:
  A  98Zr β- decay (30.7 S)  B  96Zr(3He,p)

General Comments:

In 100Mo(d,α) E=12, 23 MeV (1975BrZB,1975FoZU), excitation of 25 levels is indicated but details of this work are unavailable

α 1.5-min 98Nb isomer (1966Gu05) is discarded due to lack of confirmation in later studies (1969Hu07,1976He10)

Theory references: consult the NSR database (www.nndc.bnl.gov/nsr/) for 5 primary references, 2 dealing with nuclear structure calculations and 3 with decay modes and half-lives.

Q-value: S(2n)=14064 5, S(2p)=19767 8 (2017Wa10)
