Spectroscopic Tools Applied to Element Z = 115 Decay Chains

Nuclides that are considered to be isotopes of element Z = 115 were produced in the reaction 48 Ca + 243 Am at the GSI Helmholtzzentrum fur Schwerionenforschung Darmstadt. The detector setup TASISpec was used. It was mounted behind the gas-filled separator TASCA. Thirty correlated -decay chains were found, and the energies of the particles were determined with high precision. Two important spectroscopic aspects of the o line data analysis are discussed in detail: the handling of digitized preamplified signals from the silicon strip detectors, and the energy reconstruction of particles escaping to upstream detectors relying on pixel-by-pixel dead-layer thicknesses.
