摘要：

The 48K, 49K and 50K nuclides have been produced in high energy fragmentation and analyzed by mass spectroscopy techniques. Their half-lives have been measured as 6 ± 1 s, 1.1 ± 0.3 s and and 0.7 ± 0.3 s, respectively. The γ-rays from their radioactive decay have been observed and the corresponding γ-intensities measured. The nuclide 50K is shown to be a delayed neutron emitter. The antianalog states in the daughter Ca nuclei with a (1d 3 2)- neutron configuration, preferentially populated in the β-decay, have been located. The corresponding 1d 3 2 neutron single-particle energy is found to remain approximately constant for these neutron-rich Ca isotopes. © 1978.
