TDPAC Measurement of the quadrupole interaction of77Se in arsenic

  • S. Unterricker
  • F. Schneider


By TDPAC the quadrupole coupling constant for77Se (5/2, 248 keV, 9.3 ns) in metallic arsenic was measured to be υQ = 700 ± 60 MHz. The tabulation of electric field gradients (EFGs) for some different sp impurity host combinations shows large values for impurities with 6 valence electrons. If we assume that the selenium impurity is substituted in arsenic, then it is possible to interpret the very high υQ by the assumption of a big EFG and a large quadrupole moment (approximately 1 b) of the excited77Se nucleus.
