Alpha decay of thermally excited nuclei

RADIOACTIVITY ²¹²Po(α); calculated T_1/2 for temperatures ranging from T=0-2.4 GK using the standard scheme of a tunneling decay where the α particle tunnels through the potential barrier formed by its interaction with the daughter nucleus.

Manifestation of deformation and nonlocality in α and cluster decay

RADIOACTIVITY ²²²Ra(α), (¹⁴C); ²²³Ra(α), (¹⁴C); ²²⁸Th(α), (²⁰O); ²³¹Pa(α), (²³F); ²³²U(α), (²⁴Ne); ²³³U(α), (²⁴Ne), (²⁸Mg); ²³⁵U(α), (²⁵Ne), (²⁸Mg); ²³⁷Np(α), (³⁰Mg); ²³⁶Pu(α), (²⁸Mg); ²⁴¹Am(α), (³⁴Si); ²⁴²Cm(α), (³⁴Si); calculated T_1/2, preformation factors, penetration probabilities, half-life dependence on deformation. Studied the nonlocality effects with 2 different nuclear potential models - the energy-independent but angular momentum-dependent Mumbai potential and the energy-dependent Perey-Buck (PB) potential.

Assessment of nonlocal nuclear potentials in α decay

RADIOACTIVITY ¹⁰⁶Te, ¹⁴⁴Nd, ¹⁶⁸Pt, ¹⁸⁰W, ^210,212Po, ²⁵⁴Fm(α); calculated strong interaction potential between α particle and daughter nucleus, T_1/2, percentage decrease in α decay half-lives using three different models (Mumbai, Sao Paulo and Perey-Buck) of nonlocality, and cluster preformation probability using non-local interaction with density-dependent double-folding model. Comparison with experimental values. Use of α-decay half-lives as a complementary tool for constraining the nonlocality models.
