Nuclear Chemistry Part 1: 8 exotic lesser known radioactive decay modes with example

There are several types of exotic lesser known radioactive decay by which a radio nuclide decays and comes to ground state. Example of 8 of them are as follows:  

1. Direct Proton decay [K.P. Jackson et al, Cerny, Joseph, et al.]

53mCo (240 ms) --> 52Fe + p (1.56 MeV)

Other example

151Lu (80.6 ms) --> 150Yb + p (1.23 MeV)

2. Direct double Proton decay [Giovinazzo et al]

Other example

45Fe [Giovinazzo et al1, Borcea et al]

3. Beta (-) delayed alpha decay (Evaluated data)

4. Beta (-) delayed neutron decay (Evaluated data, Rutherford et al)

Other example: 17N half life: 4.173s

5. Beta (+) delayed Proton decay (β+(p)) (Orrigo et al)

6. Beta (+) delayed single Proton decay β+(2p) [Xu et al, Wang et al]

 

7. Beta (+) delayed two Proton decay (β+(2p))

8. Cluster decay [Rose, H. J. et al, Santhosh, K. P., et al, D. Weselka et al]

Other examples

228Th --> 208Pb + 20O

238Pu --> 208Pb + 30Mg 

226Ra --> 212Pb  + 14C
