Colour-magnitude diagrams are presented for the first time for L 32 , L 38 , K 28 ( L 43 ) , K 44 ( L 68 ) and L 116 , which are clusters projected onto the outer parts of the Small Magellanic Cloud ( SMC ) .
The photometry was carried out in the Washington system C and T _ { 1 } filters allowing the determination of ages by means of the magnitude difference between the red giant clump and the main sequence turnoff , and metallicities from the red giant branch locus .
The clusters have ages in the range 2-6 Gyr , and metallicities between -1.65 < [ Fe/H ] < -1.10 , increasing the sample of intermediate-age clusters in the SMC .
L 116 , the outermost cluster projected onto the SMC , is a foreground cluster , and somewhat closer to us than the Large Magellanic Cloud .
Our results , combined with those for other clusters in the literature , show epochs of sudden chemical enrichment in the age-metallicity plane , which favour a bursting star formation history as opposede to a continuous one for the SMC .
