Abstract A new isomeric state in237Np has been discovered at an excitation energy of (945.3±0.2) keV withT 1/2 =(711±40) ns. Six gamma-ray lines have been measured depopulating the isomeric state to known levels in237Np. The comparison of the measured absolute gamma-ray transition probabilities with empirical values yields as most probable spinI andK assignmentI=K=13/2 for this isomeric state. It is most likely a 1-proton-2-neutron quasiparticle state 13/2−π5/2+ [642] +ν7/2− [743] + ν 1/2+ [631]. However, a one-quasiparticle 11/2− [505] configuration for the isomer cannot be excluded.
