The zeros in dipole and quadrupole matrix elements of photoeffect from the ns/sub 1/2/ subshells of uranium approach common positions as n..-->..infinity. This is an illustration of the more general feature that for sufficiently large n/sub 0/ photoeffect cross sections and angular distributions from nJL subshells, aside from the bound-state normalization factor which scales the cross section, are the same for all n>n/sub 0/ (J,L fixed) except for energies very close to threshold. This behavior can be expected for all subshells and all elements and for all multipole matrix elements.
