Abstract
We achieved excitation of the first excited state of 40K and confirmed both energy and lifetime. Furthermore, we observed nuclear resonant inelastic scattering by 40K in a powdered KCl sample at room temperature using a high-resolution monochromator. The time spectrum of the nuclear resonant forward scattering was measured at 50 K. Our observations of nuclear resonant inelastic and forward scattering by 40K make electronic and dynamic studies for potassium practical. The measurements of nuclear resonant scattering for the radioactive 40K nuclide will enable and lead to further studies of other radioactive nuclides.
