Based on 7.33 fb(-1) of e(+)e(-) collision data taken at center-of-mass energies between 4.128 and 4.226 GeV with the BESIII detector, we measure the branching fraction of D-s*(+)-> D-s(+)pi(0) relative to that of D-s*(+) -> D-s(+)gamma to be (6.16 +/- 10.43 +/- 10.18)%.

Abstract
Based on 7.33 fb(-1) of e(+)e(-) collision data taken at center-of-mass energies between 4.128 and 4.226 GeV with the BESIII detector, we measure the branching fraction of D-s*(+)-> D-s(+)pi(0) relative to that of D-s*(+) -> D-s(+)gamma to be (6.16 +/- 10.43 +/- 10.18)%. The first uncertainty is statistical and the second one is systematic. By using the world average value of the branching fraction of D-s*(+) -> D-s(+) e(+)e(-), we determine the branching fractions of D-s(*+) -> D-s(+)gamma and D-s(*+) -> D-s(+)pi(0) to be (93.57 +/- 10.38 +/- 10.22)% and (5.76 +/- 10.38 +/- 10.16)%, respectively.
