Using data with the Suzaku XIS and HXD , spectral studies of short bursts from the soft gamma repeater SGR 0501 + 4516 were performed .
In total , 32 bursts were detected during the \sim 60 ks of observation conducted in the 2008 August activity .
Excluding the strongest one , the remaining 31 bursts showed an average 2–40 keV fluence of 1.0 _ { -0.5 } ^ { +0.3 } \times 10 ^ { -9 } erg cm ^ { -2 } .
A 1–40 keV spectrum summed over them leaves significant positive residuals in the HXD-PIN band with \chi ^ { 2 } /d.o.f .
= 74/50 , when fitted with a two-blackbody function .
By adding a power law model , the fit became acceptable with \chi ^ { 2 } /d.o.f .
= 56/48 , yielding a photon index of \Gamma = 1.0 _ { -0.3 } ^ { +0.4 } .
This photon index is comparable to \Gamma = 1.33 _ { -0.16 } ^ { +0.23 } \citep enoto2010a for the persistent emission of the same object obtained with Suzaku .
The two-blackbody components showed very similar ratios , both in the temperature and the emission radii , to those comprising the persistent emission .
However , the power-law to two-blackbody flux ratio was possibly higher than that of the persistent emission at 2.6 \sigma level .
Based on these measurements , average wide-band properties of these relatively weak bursts are compared with those of the persistent emission .
