RE: Nuclear Isomer Decay: A Possibility for Breakthrough Space

["Huneycutt, Scott E" <Scott.Huneycutt@pnl.gov>]

The mass is apparent from DeBroglie's equation relating wavelength to mass

gamma = h/mv where h is Planck's constant.

Gammas have no Rest Mass.  The do have apparent mass.

>I thought gammas had no mass..... how can there be a recoil momentum?

Einstein's relativity theory predicts that photons have momentum p = E/c.
This prediction was first confirmed by Compton scattering, and has since
been confirmed by many other observations.
