Summary, etc. |
<p>In present work, we have calculated the hindrance factors of 182 even-even alpha emitters using Preston’s formulation of alpha decay probabilities and presented HFs systematics of 1<sup>-</sup> and 3<sup>-</sup> states in reflection asymmetric even-even quadruple-octupole deformed nuclides (A~216-230). The calculated HFs of both 1<sup>-</sup> and 3<sup>-</sup> states decrease with reduction in neutron number and this decrease is attributed to onset of intrinsic reflection asymmetry. There is a trend reversal for 1<sup>-</sup> states at N=132 (<sup>218</sup>Ra) and N=134 (<sup>220</sup>Rn), which might be a possible indication of departure from static octupole deformation. Similarly, HFs systematics is discussed for <sup>224-230</sup>Th and <sup>232-236</sup>U isotopic chains along with 2<sup>+</sup> states observed in daughter nuclei in N=132-146 isotonic chains.</p> |
