Spontaneous fission of Cm244 with emission of a long-range alpha particle

The emission probabilities of long range alpha particles from even–even244–252Cm isotopes

“…The turning points where m is the nucleon mass and 1 A , 2 A , 3 A are the mass numbers of the three fragments. The relative yield can be calculated as the ratio between the penetration probability of a given fragmentation over the sum of penetration probabilities of all possible fragmentation as follows,…”

“…Malkin et al [3] have measured 400 cases of ternary fission of 244 Cm with the emission of long range alpha particle, and have obtained the most probable energies for light and heavy fragments as (100 ± 8)MeV and (77 ± 6)MeV respectively.…”

α-accompanied cold ternary fission ofPu238–244isotopes in equatorial and collinear configuration

“…[1]), where the authors have computed the number of alpha particles emitted in coincidence with the fission of 235 U and 239 Pu isotopes. Later Perfilov et al [2][3][4] have studied the energy spectra of alpha particles for ternary fission of different isotopes of uranium, plutonium and curium isotopes and in 1964 Malkin et al [5] have studied the spectrum of long range alpha particle from the spontaneous fission of 244 Cm isotope and obtained the most probable energy of the alpha particle as 15.8MeV. The angular distributions and the energy distributions of long range alpha particles emitted from the spontaneous ternary fission of 252 Cf isotope have been studied using the statistical theory of nuclear fission by Vitta [6] and the multiparameter measurements are performed by Theobald et al, in order to compute the kinetic energies and relative angles of the three particles emitted in the ternary fission process [7].…”

“…In terms of spheroidal co-ordinates, Delion et al [17] studied the dynamics of cold ternary fission of 252 Cf isotope with light charged particle as 4 He and 10 Be. The clusters heavier than alpha particles like 5 He, 7 He and 8 Li that formed during the spontaneous ternary fission of 252 Cf has been studied by Kopatch et al [18].…”

Deformation effects in the alpha accompanied cold ternary fission of even-even 244-260Cf isotopes

“…The light charged particle accompanied fission also termed as ternary fission is a fission process in which three fragments are formed and it has been an interesting area for discussion under both experimental and theoretical efforts for the last few decades [1][2][3][4][5][6][7][8]. The cold alpha accompanied ternary fragmentation of 248 Cm isotope was studied by Sandulescu et al [9] using double folding potential generated by Coulomb plus M3Y nucleon-nucleon forces.…”
