Theγ-decay modes of38Ar levels withE x ≦11,630keV and of42Ca levels withE x ≦10,036keV have been studied using the35Cl(α, pγ) reaction at 16MeV and the39K(α, pγ) reaction at 15.14 MeV, respectively. In both nuclei the number of states withJ≧6 exceeds fifty. Weak coupling calculations of the Bansal and French type reproduce the density of high-spin states. The success of the model implies that the excitations of up to four particles from thed3/2 into thef7/2 shell play a role in both nuclei. The structure of deformed states was found to be predominantly 4p/s 6h in38Ar and 4p/s 2h in42Ca, respectively.
