Summary Theoretical information on possible waves reflected from the terrestrial inner core is obtained from the partitioning of energy of P waves incident on its surface. The amplitudes of PKiKP and PKIIKP are compared with those of PKIKP for allowable density and rigidity contrasts. A similar comparison for PKJKP is made in order to show the dependence of its amplitude on Poisson's ratio in the inner core. The phase PKiKP is not likely to possess appreciable energy compared with PKIKP except at distances greater than 105°. Near the anticentre, PKIIKP may have an amplitude about half that of PKIKP observed in the neighbourhood of 140°. Some observations bearing on the PKiKP phase are discussed.
