The position of a nuclear level perturbing the Coulomb spectrum can be calculated in the analytic theory of nuclear level shifts/sup 1//sup en-dash//sup 3/ from the level shift of a hadronic atom. This is illustrated by the example of the K/sup -4/He atom. Experimental 2p-level shifts/sup 4//sup ,//sup 5/ suggest that this system may have a weakly-bound p-state with binding energy and width Epsilonapprox...gamma..approx.0.5 MeV. The probabilities of radiative transitions to this level and the cross section for its creation in nuclear reactions on /sup 6/Li are calculated. The possible existence of states in which K/sup -/ and p-bar are weakly bound to other light nuclei is examined. An exact solution is obtained for a model Coulomb problem with short-range interaction, and is used to determine the range of validity of the initial approximations.
