19.I. Marklund and B. Lindstrom [Nucl. Phys. 40, 329 (1963)] measure an energy of for this transition. (Their quoted value has been modified slightly from due to a re‐evaluation of the wavelength of their calibration line.)20
19.F. Boehm and C. Gunther (private communication, 1965) have measured this line by direct comparison with the x rays,20 obtaining the value
