The probability of non-radiative decay of the 3d level in muonic 237Np

The study of prompt and delayed muon induced fission

“…In heavy nuclei, the intensities of the radiationless 3d~ ls (E~9 MeV) and 2p--+ ls (E,--6.5 MeV) tran- sitions are in the range of 10 to 20% per/t-atom formation [26][27][28]. Radiationless transitions from higher levels are also possible, but their total intensity is below 3%/#-stop [29].…”

Nuclear excitation and prompt fission in muonic238U

“…transitions has been investigated both theoretically [-2-4] and experimentally [5][6][7][8]. transitions has been investigated both theoretically [-2-4] and experimentally [5][6][7][8].…”

The probability of prompt and delayed fission of muonic237Np

“…transitions (2p~ls) and (3d~ls) have to be known. For the quadrupole transition this value has been determined by measuring the fraction of missing muonic X-rays coincident with the (2p~ls)-transition [8]. To determine the fraction of the n.r.…”

“…atomic transitions, and delayed fission, induced by the nuclear capture of the muon from the 1 sorbit. Non-radiative transitions can selectively excite the nucleus in energy and in multipolarity [1][2][3][4][5][6][7][8]. This excitation is a unique tool to investigate the static properties of heavy muonic nuclei, i.e.…”
