  Statistical approach for proton and neutron have been used to study the low
energy properties of nucleons. Nucleons is assumed as a composite system of
three quarks and "sea" where sea is assumed to be in S-wave consisting of
quark-antiquark pairs (u]\bar{u},d\bar{d} only) and gluons. Here the
contributions from scalar, vector and tensor sea is taken into consideration to
find {\alpha} and {\beta}. Distribution of spin among valence quarks and
sea-quark for proton and neutron are denoted by I_1^pand I_1^n respectively.
Statistical model predicted the values as 0.132 and -0.011 which is close to
EMC experimental value 0.136 and -0.013 for I_1^p and I_1^n respectively.
Although the statistical model predictions give close to EMC data for neutron
spin distribution. The results have also been compared with the Simple quark
model results that matches well with SU(6) model..
