Estimation the Mass of Radioactive Element 56Ni Nucleosynthesis In SN 2018zd Explosion Epoch

SN 2018zd is the type II core-collapse supernova .we calculate its total energy according to curve light of SN 2018zd by E.Callis et al presented.In the case of considering de-excited energy of electron capture, we estimate thermal energy released by a nucleon of <inline-formula><alternatives><math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="M1"><mmultiscripts><mrow/><mprescripts/><mrow/><mrow><mn mathvariant="normal">56</mn></mrow></mmultiscripts><mi>N</mi><mi>i</mi></math><graphic specific-use="big" xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="alternativeImage/A046509D-5E9F-46fd-8757-BABAF530BD67-M001.jpg"><?fx-imagestate width="4.99533367" height="2.28600001"?></graphic><graphic specific-use="small" xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="alternativeImage/A046509D-5E9F-46fd-8757-BABAF530BD67-M001c.jpg"><?fx-imagestate width="4.99533367" height="2.28600001"?></graphic></alternatives></inline-formula> through a chain electron capture reaction based on the theory of nuclear shell.
