“…made by Rose and Jones [10] with a semiconductor detector telescope, was confirmed with a similar technique by Alexandrov et al [11] and with a more refined experimental setup (magnetic spectrometer) by Gales et al [12] and by Kutschera et al [13]. Price et al [14] and Barwick et al [15] started a series of experiments with a very promising technique of solid state nuclear track detectors.…”

Experimentally observed enhanced 14C and 24Ne emission rates from even-even parents in comparison with that from even-odd or odd-even nuclei are explained in the framework of the analytical superasymmetric fission model, by taking various prescriptions for the zero point vibration energy of even-even, even-odd, odd-even and odd-odd emitters. Longer half-lives than previously computed are obtained by extrapolating the present prescriptions to emitted clusters heavier than 24Ne. PACS: 23.90. + w; 27.90. + bThe analytical superasymmetric fission model (ASAFM) has been developed, since 1980, as an efficient alternative to other three methods used to predict new decay modes by spontaneous heavy cluster emission. The various models were reviewed by Sandulescu et al. Two of the more than 140 new decay modes, namely 14C and 2'~Ne radioactivities, are already experimentally confirmed in good agreement with the calculated half-lives and branching ratios relative to alpha decay. They have been found in Ra-isotopes with A=222, 223, 224, 226 and in 23~ 131pa, 232'233U respectively. The pioneering experiment * Supported in part by Bundesministerium ffir Forschung und

“…Examples from the first category are two members of the decay chain of 231 Pa: 227 Ac (T = 21.77 y) and 227 Th(T = 18.72 d), which generate 223 Ra(7 = 11.43 d). An activity of 210 μ0 (about 300 times stronger than that used by Rose and Jones) of 223 Ra has been obtained [14] with a thin deposit of 227 Ac having a diameter of 8 mm.…”

“…The solution adopted in the elegant experiments performed at Orsay, by Hourani and his colleagues [14,26,27,17,20], was to deflect the unwanted 4 He ions, simply or doubly ionized, by a strong magnetic field produced in the spectrometer SOLENO [28] and to select only 14 C clusters to reach the detector in the focal plane. With this unique instrument it was possible to discover the fine structure in cluster decay [29][30][31]21] discussed by Martin Greiner and Werner Scheid [32].…”
