Abstract In the present work, a two-parameter empirical formula is proposed, based on Geiger-Nuttall law, to study two-proton ( ) radioactivity. Using this formula, calculated radioactivity half-lives are in good agreement with experimental data as well results obtained by Goncalves et al . [ Phys. Lett. B 774 , 14 (2017)] using effective liquid drop model (ELDM), Sreeja Eur. J. A 55 33 (2019)] four-parameter and Cui Rev. C 101 : 014301 (2020)] generalized (GLDM). addition, extended predict...
Abstract In this study, based on the Gamow-like model, we systematically analyze two-proton ( ) radioactivity half-lives of nuclei near or beyond proton drip line. It is found that calculated results can reproduce experimental data well. Furthermore, using predict possible candidates whose energetically allowed observed but not yet quantified in latest table evaluated nuclear properties, i.e., NUBASE2016. The predicted are good agreement with those from other theoretical models and empirical...
187Ta (𝑍=73, 𝑁=114) is located in the neutron-rich 𝐴≈190 region where a prolate-to-oblate shape transition via triaxial softness predicted to take place. A preceding work on 𝐾𝜋=(25/2−) isomer and rotational band which decays carried out by same collaboration revealed that axial symmetry slightly violated this nucleus. This paper focuses higher-lying isomer, was previously identified at 2933(14) keV mass measurements with Experimental Storage Ring GSI. The of interest has been populated...
In the present work we systematically study half--lives of proton radioactivity for $51 \leq Z 83$ nuclei based on Gamow--like model with a screened electrostatic barrier. this there are two parameters while considering effect Coulomb potential Hulthen i.e. effective nuclear radius parameter r_0 and screening a. The calculated results can well reproduce experimental data. addition, extend to predict 16 in same region within factor 2.94, whose energetically allowed or observed but not yet...
The present work is a continuation of our previous paper [J.-G. Deng, et al., Chin. Phys. C, 41: 124109 (2017)]. In the work, α decay half-life unknown nucleus 296Og predicted within two-potential approach and hindrance factors all 20 even-even nuclei in same region as 296Og, i.e. proton number 82<Z<126 neutron 152<N<184, from 250Cm to 294Og, are extracted. prediction 1.09 ms factor 5.12. addition, based on latest experimental data, new set parameters for this region, considering shell...
Abstract In the present work, we predict α decay half-lives of unknown even-even nuclei 296–308 120 within two-potential approach, whose energy Q is calculated using WS3+ mass model. To reduce deviations between predictions and experimental data due to nuclear shell effect, analytic formula hindrance factor introduced parameters had been extracted from in region 82 < Z ≤ 126 152 N 184 our previous work [Deng et al ., Chin. Phys. C 42 (2018) 044102]. addition, for comparing, use a type...
In the present work, combining with Geiger-Nuttall law, a two-parameter empirical formula is proposed to study two-proton (2p) radioactivity. Using this formula, calculated 2p radioactivity half-lives are in good agreement experimental data as well ones obtained by Goncalves et al: ([Phys. Lett. B 774, 14 (2017)]) using effective liquid drop model (ELDM), Sreeja ([Eur. Phys. J. A 55, 33 (2019)]) four-parameter and Cui Rev. C 101: 014301 (2020)]) generalized (GLDM). addition, extended predict...
