We report the first INTEGRAL timing and spectral analysis of the high mass X-ray binary source 2S 0114+65 at high energies (5-100keV). The pulse period was found at 2.668 h with a high pulsed fraction, ∼80% in both the 20-40keV and 40-80keV energy bands. The spin-up trend over ∼8 years was measured to be {dot}(P)=-8.9x10^–7s/s. The hard X-ray spectrum obtained with JEM-X/ISGRI is well described by a high energy exponential cut-off power law model where the estimated luminosity is 1.8x10³⁶erg/s in the 5-100keV energy band, for a source distance of 7.2kpc. We tentatively identify a cyclotron resonance scattering feature at ∼22keV with one harmonic, implying a magnetic field of ∼2.5x10¹²G.
