The open question suggested by Murch in [1] is how the vectors a(1),a(2),..
., can be obtained from the scattering data for some wavenumbers k and for
all incident waves. In this paper, it is suggested how the constants ao and
al can be used for reconstruction from the scattering data with the other
a(n), n greater than or equal to 2 being ignored. Numerical implementation
is presented for comparison with Murch's work. (C) 1999 Elsevier Science Lt
