      In this paper, the inverse spectral problem for the operator [ Lλ generated by the differential expression (formula presented) is investigated in the space L2 (ℝ). Here the coefficients p(x), q(x) are almost periodic functions whose Fourier series are absolutely convergent and the sequence of Fourier exponents (which are positive) has a unique limit point at +∞. The set of spectral data [Formula Presented] of the operator Lλ is defined and the problem of finding the coefficients p(x), q(x) from these sequences is considered. © 2023, Institute of Mathematics and Mechanics, National Academy of Sciences of Azerbaijan.
