Hey everyone,(adsbygoogle = window.adsbygoogle || []).push({});

I've learned about double beta decay and neutrinoless double beta decay recently. So we have two "conditions" for decay,2vdecay and0vdecay. Now, to the question I have:

There have been a lot of experiments measuring2vdecay rates, and there have been many experiments concerning a limit on Majorana mass for neutrinos in0vdecay. We have the following equation for2vdouble beta decay rates:

(T^{2v}_{1/2})^{-1}=G_{2v}|M_{2v}|^{2}

WhereGis the phase space factor andMis the nuclear matrix element.

So I've acquired this list of values that correspond to theGandMvalues for 2ν Double Beta Decay values, and I am calculating the rate for the 2v Decay of 48Ca:

M value (Nuclear Matrix Element):~0.05

(G9.7 X 10^{2v})^{-1}value:^{16}y x MeV^{-2}

So my question is, in order to acquire the decay rate, do all I need to do is multiply these values? I know it seems silly to ask, but please bear with me. I am a high school student who is learning all of this physics for the first time (at a college), it just seems a little crazy that it could just be as simple as that

Thank you in advance!
