| Popis: |
The half lives of the following excited nuclear states have been measured with delayed coincidence techniques: 145 keV level in Pr141: T 1 2 = (19 ± 2) × 10 −10 sec 163 keV level in La139: T 1 2 = (15 ± 1) × 10 −10 sec 160 keV level in I131: T 1 2 = (9 ± 1) × 10 −10 sec 279 keV level in Tl203: T 1 2 = (1.2 ± 0.3) × 10 −10 sec Theoretical points of view about these l-forbidden (Δl = 2, Δj = 1) M1 transitions are briefly reviewed and it is shown that the matrix elements derived from the experimental half lives are in reasonable agreement with expectations based on the spin-orbit coupling encountered in the shell model. |
