Анотація

Розглядається протонний розпад майже всiх надважких ядер з атомними номерами Z = 104–126. Розраховано енергiю, що вивiльняється в такому розпадi (QP), коефiцiєнт проникнення (P), коефiцiєнт нормування (F) та перiоди напiврозпаду. Останнi бiльшi, нiж для iнших каналiв розпаду, таких як альфа-розпад та спонтанне дiлення. У порiвняннi з iншими каналами розпаду, протонний розпад не є домiнуючим в областi надважких ядер. Це означає, що надважкi ядра можна вважати стабiльними вiдносно протонного розпаду.
