Abstract
Measurements of theK,L I,L II andM I conversion lines of the 687.7 keV transition in236U are evaluated within the electron penetration formalism. The spin-parity assignment of the octupole bandhead is found to be 1− in accordance with reaction data, and an assignment of 2− to the 687.7 keV state is ruled out. The penetration matrix element ∥η∥ has the value of 13.5 for theK-shell and increases slightly for higher main shells. An estimate of the anomalous amplitudes is compared with values reported for transitions in the odd even actinide nuclei. Furthermore electron conversion data for the 1−→2+ and 1−→4+ transitions are given.
Radioactivity236U from235U(n,e −); measured: conversion electron decay; deduced: conversion coefficients fromK, L andM shells; evaluated: dynamic matrix elements.
