Abstract

By using a ²²⁵Ac source produced at the electromagnetic separator Isolde we collected on our track-recording glass detectors 305 ¹⁴C events from the radioactive decays of ²²⁵Ac and its daughter ²²¹Fr and obtained, for ²²⁵Ac, a branching ratio $B(^{14} C/α) = (6.0 ± 13) × 10^{−12}$ . Our result suggests that such a decay from an odd proton nucleus is dominated by transition to the ground or to the first excited state of daughter nucleus.

Cluster radioactivity in platinum isotopes
2023, Nuclear and Particle Physics Proceedings
We studied the cluster radioactivity in Platinum isotopes using different proximity potentials in the Coulomb Proximity Potential Model (CPPM). Cluster decay with cluster nuclei like ⁸Be and ¹²C from different Platinum isotopes are considered. Logarithmic values of half-life are calculated using CPPM with different proximity potentials and compared with the half-life from the Universal Decay Law (UDL).
Heavy particle radioactivity of superheavy element Z = 126
2021, Nuclear Physics A
The concept of heavy particle radioactivity is studied using modified generalised liquid drop model (MGLDM) in the superheavy element Z = 126. The eight different proximity functions and different mass excess values were used to evaluate cluster/HPR. The logarithmic half-lives using different proximity functions and mass excess values are compared with that of experiments. The HPR of ⁶⁰Ni to ¹⁰²Ru have been studied in the superheavy region ${}^{306}126$ to ${}^{326}126$ . The HPR half-lives has been compared with the different decay modes such as α-decay, β-decay and spontaneous fission. 9 HPR emitters, 4 α emitters, 1 $β^{+}$ emitter and 7 spontaneous fission nuclei were identified in the superheavy nuclei ${}^{306 - 314}126$ , ${}^{315 - 318}126$ , ${}^{319}126$ and ${}^{320 - 326}126$ respectively.
Clusters decay half-live of various heavy deformed nuclei with mass numbers in the range 221 ≤ A ≤ 242
2020, Chinese Journal of Physics
Decay half-live of several clusters between ¹⁴C and ³⁴Si emitted from various heavy deformed nuclei with mass numbers in the range 221 ≤ A ≤ 242 are calculated using nuclear Woods-Saxon (V_N(r, θ)), Coulomb (V_C(r, θ)) and rotational (V_l(r)) potentials considering deformation for both daughter and cluster and spherical configuration for them. Half-live of these decays are also obtained using a semi-empirical formula. Obtained results considering deformation are compared with the half-live of spherical configuration, results of a semi-empirical formula as well as the available experimental data. The comparison indicates that the calculated half-lives considering deformation are better agreed with the experimental data than the results of spherical configuration and the out put of semi-empirical formula. Also, The obtained results using deformation is better confirmed the Geiger-Nuttall low of alpha decay, especially for emission of light clusters as expected.
Solid-state nuclear track detectors
2020, Handbook of Radioactivity Analysis: Volume 1: Radiation Physics and Detectors
Part 1 describes the elements of solid-state nuclear track detectors (SSNTDs) including detector materials (crystals, glasses, polymers), recordable particles (protons, α-particles, fission fragments, heavy ions, neutrons, exotic particles), track formation mechanisms, track etching, particle identification, and track measuring instruments. Part 2 describes applications in nuclear physics, astrophysics, cosmic ray physics, fission track dating and geothermal chronology, medical science, radiation dosimetry, Rn monitoring, environmental sciences, and nanotechnology. Attention is paid to the newly emerged fields: track formation mechanism studied by means of infrared (IR) absorption spectrometry, laser acceleration, laser inertial confinement fusion, nuclear forensics and safeguards. The internal structure in this chapter is closely linked between materials, particles, and applications; when describing one of these, the other two are introduced. The above structure of this chapter was organized for the benefit of the reader by providing the current principles and techniques together with the broad research fields of application of SSNTDs. Numerous detector materials and their parameters and applications are provided. Essential literature references are provided for detailed information on breakthroughs and recent advances.

Cluster formation probability in the trans-tin and trans-lead nuclei
2010, Nuclear Physics A
Within our fission model, the Coulomb and proximity potential model (CPPM) cluster formation probabilities are calculated for different clusters ranging from carbon to silicon for the parents in the trans-tin and trans-lead regions. It is found that in trans-tin region the ¹²C, ¹⁶O, ²⁰Ne and ²⁴Mg clusters have maximum cluster formation probability and lowest half lives as compared to other clusters. In trans-lead region the ¹⁴C, ^18,20O, ²³F, ^24,26Ne, ^28,30Mg and ³⁴Si clusters have the maximum cluster formation probability and minimum half life, which show that alpha like clusters are most probable for emission from trans-tin region while non-alpha clusters are probable from trans-lead region. These results stress the role of neutron proton symmetry and asymmetry of daughter nuclei in these two cases.
