Abstract

The beta decay of the very neutron-deficient isotope Sn-101 was studied at the GSI on-line mass separator using silicon detectors for recording charged particles and germanium detectors for gamma-ray spectroscopy. Based on the beta-delayed proton data the production cross-section of 101Sn in the 5 Cr-50+ Ni-58 fusion-evaporation reaction was determined to be about 60 nb. The half-life of (101) Sn was measured to be 1.9(3) s. For the first time beta-delayed gamma-rays of Sn-101 were tentatively identified, yielding weak evidence for a cascade of 352 and 1065 keV transitions in In-101. The results for the Sn-101 decay as well as those from previous work on the Sn-103 decay are discussed by comparing them, to predictions obtained from shell model calculations employing a new interaction in the Sr-88 to Sn-132 model space.
