Deleted Reference

I deleted the following:

Because of this, a type of nuclear battery employing germanium and radon (as an alpha source) has been proposed.

As I don't see any evidence that this was anything more than an idea proposed by one group. It also doesn't make much sense as a nuclear battery, since the most stable isotope of radon has a half-life of less than 4 days. It wouldn't last very long, unless you were able to constantly replenish the radon. It seems like you'd want a much longer-lived alpha source. XinaNicole (talk) 06:16, 27 May 2011 (UTC)

Stability of Germanium EO isotopes

The central mass value stable isotope of 32Ge Germanium is EO32Ge73 with 9 extra neutrons and 7.76% constituency. However as the number of extra neutrons is increased the radioactivity of the OE isotopes is noted to first decrease to 1.38 hours (3.70 log seconds) at EO32Ge75 and then to rise again to 11.25 hours (4.61 log seconds) at EO32Ge77. This is an irregularity in the EO stability data for this element which usually slopes steadily away down the sides of the central tendency of a stability profile chart.WFPM (talk) 01:14, 20 December 2011 (UTC)

A Log second half-life stability chart of the Wiki data shows clearly this and other stability characteristic tendencies of this (and the other) elements. It is not understood why this method of presenting the reference data is not permitted as a better way to look at and understand this data.17:15, 17 April 2013 (UTC)

Unclear statement

What does this statement mean?

"Angular momentum or 3rd order sub particles are omitted as spin(2)=0,45,45."

"Iso's" button associated with germanium does not function.

I tried the "Iso's" button for many other elements, and they work correctly. 71.8.174.161 (talk) 20:14, 2 October 2019 (UTC)
