The first 8{sup +} state in the mass-80 nuclei below the N=50 neutron shell has a g{sup 2}4/2 structure. For near-spherical and oblate nuclei, this is a neutron-hole configuration; for prolate nuclei this appears to be a rotation-aligned proton configuration. The character of these states must be established by g-factor measurements since the nuclear shape changes too rapidly with nucleon number for blocking arguments or systematic trends to be reliable. A number of such measurements have been carried out on some neutron-deficient isotopes of Se, Kr, Ar and Zr by applying the transient magnetic field method to nuclei produced in heavy-ion reactions. The analysis yields either average g-factors for states above an allignment or, in favourable cases, g-factors of the individual states. The results may be used to deduce the shape change from nucleus to nucleus, and even from band to band in this interesting region.
