摘要：

In high-resolution measurements of delayed protons following the beta-decays of 32Ar and 33Ar we have observed significant line broadening caused by the beta-nu recoil motion of the daughter nuclei. The measured line shapes agree well with the calculation for both Fermi and Gamow-Teller decays and yield new spectroscopic information on the transitions and excited states involved. For the Gamow-Teller strength in the beta+-decay of 33Ar to the isobaric analogue state in Cl-33 an upper limit of B(GT) < 0.029 was determined.
