“…where ∆r p and ∆r n are the differences between the actual radius and the smooth description of the radius-value for the proton and neutron, respectively, following the radius parametrization by Dobaczewski et al [41] (see section 2, equation 14). In this way, values of δR C have been estimated as 0.02 fm for 22 Ne, 30 Mg, and 32 Si, 0.03 fm for 20 O, 23 F, and 34 Si, and 0.04 fm for 14 C, [24][25][26] Ne, and 28…”

“…The advance in theoretical treatment of exotic decays has motivated several exper-imental groups to develop new methods for heavy-ion identification and half-life measurements in investigating for rare cases of exotic radioactive decays of extremely small predicted branching ratio relative to alpha decay in the range ∼10 −16 -10 −9 . Eleven different heavy clusters ( 14 C, 20 O, 23 F, 22,[24][25][26] Ne, 28,30 Mg, 32,34 Si) have been detected so far in the radioactive decay of translead parent nuclei. The reader is referred, for instance, to publications by Zamyatnin et al .…”

“…One of the approaches to describe the cold cluster radioactivity of nuclei is a nonadiabatic treatment similar to alpha decay (alpha-decay-like model, ADLM) (the other approach is an adiabatic treatment similar to superasymmetric fission [24,25]). In view of the excellent performance of our quantum-mechanical tunneling, ADLM, to all cases of alpha decay as mentioned in the precedent paragraph, we thought it worthwhile to extend our original model [29] also in systematizing the half-lives of all cases of cluster emission so far experimentally investigated.…”

Radioactive decay of nuclei by the emission of heavy ions of C, N, O, F, Ne, Na, Mg, Al, Si, and P isotopes (known as exotic decay or cluster radioactivity) is reinvestigated within the framework of a semiempirical, one-parameter model based on a quantum mechanical, tunnelling mechanism through a potential barrier, where both centrifugal and overlapping effects are considered to half-life evaluations. This treatment appeared to be very adequate at fitting all measured half-life values for the cluster emission cases observed to date. Predictions for new heavy-ion decay cases susceptible of being detected are also reported.

“…The model presented here belongs to the cluster type [3][4][5][6][7][8][9][10]. As assumed, the ground state of nucleus has a small admixture of the cluster-state components [11][12][13][14][15][16].…”
