Pleas PLease help me!
FDor charge exchange production of postironium a beam of lithium atoms will be directed through a positron cloud by a lasser beam. A 0.01W laser beam traveling in the +X direction with beam diameter of 0.01m is abosorbed by the atoms traveling in the -X direction.
What ithe momentum vector of a photon?
Power = Energy/Time and Energy/ c = momentum of photon
so Pt / c = momentum of photon (YES??)
Over one second the momentum of the photon is 0.01W/ 3e+8 = 3.33 x 10^-11 kg m/s
What is the number of photons required to stop Li atom at 500m/s
Assume all the Li atom will abosrod al the photns of the same wavelength and stop it
[tex] M_{Li} V_{Li} = Np_{Photon} [/tex] but his yeidls a non integer
so is this wrong or is that the lithium atom cannot abosrb a photn of this wavelength??
