Abstract

Levels in ⁴¹Ca and ⁴¹K were populated using the reactions ³⁸Ar( alpha ,n)⁴¹Ca and ³⁸Ar( alpha ,p)⁴¹K. Solid ³⁸Ar targets were produced using a ⁴He refrigerator system at a mean temperature of 14K. Gamma-gamma coincidence data were collected at E_alpha=10.50, 11.50 and 15.00 MeV to study principal decay modes. In ⁴¹Ca new gamma decays from levels at 3975 and 4519 keV were found. Mean lifetimes were measured using the Doppler-shift attenuation method at several beam energies. Data were obtained for 36 levels in ⁴¹Ca and 21 levels in ⁴¹K.
