  For the newly discovered ironbased superconductors we propose a one band
model for conduction band with first and secondnearestneighbor electron
hoppings with two types of d wave and three types of s wave pairing symmetries
for the superconductivity. We have calculated the Greens functions from which
the temperature dependent superconducting (SC) gap and tunneling conductance
are calculated and computed numerically. The evolution of the SC gap and the
tunneling conductance spectra are investigated for different model parameters
of the system.
