[@Cui97]. However, the pulsations may not cease completely even in the propeller phase [@Neg00]. Spectral hardening, which was observed in the low state spectra of NS soft X-ray transients like Aql X-1 may be interpreted as the sign of propeller stage [@Zha98]. While anti-correlation of spectral power law index with the X- ray flux (i.e. softening of the spectra) might be the sequence of mass accretion rate changes [@Mes83; @Har84]. In this case, neither a transition to propeller stage nor an accretion change is needed to explain the softening in the spectrum with decreasing flux [@Ina04]. Consequently, decrease in mass accretion rate with a softening in the spectrum does not lead to any significant changes in pulse profiles and pulse fraction [@Bay02]. In the case of 2S 1417-62 spectral softening accompany the changes in pulse profiles and pulse fractions that may be the result of not only accretion rate changes but also accretion geometry changes for the low flux parts, which occur just before the periastron for which the NS should have accreted almost all of the accretion disc material around it. Correlation between spin-up rate and X-ray flux in different energy bands has been observed in outbursts of different
