ACCORDING to the Fermi theory of β-decay, the β-curve representing the number of electrons with a given energy lying in the interval of the transition energy of the nucleus, is governed by a ...

This sensitive β-decay experiment was utilized to constrain the spins assigned for low-lying energy levels of 158Pm and the ground state of 158Pm. A correlation method was employed to deduce the ...
