The spin of the 2.705 MeV state was found to be {7}/{2}. The level scheme of Na 23 up to 4 MeV, its ground state magnetic moment, beta and gamma transition probabilities are compared with the predictions of the collective model including (a) draw the decay scheme of 55 Cs 137 Calculate the conversion coefficient Calculate the K-shell conversion-electron energy if the K-shell binding energy is 37 keV What is Auger electron emission and with what process does it compete? 23 Naのみが安定同位体であり、単核種元素かつモノアイソトピック元素であると考えられる。 標準 原子量 は22.98976928(2) u 。 ナトリウムは2種の 放射性 宇宙線生成同位体を持つ( 22 Na, 半減期 = 2.605 年と 24 Na , 半減期 ≈ 15 時間)。 1 Decay Scheme Cs-137 disintegrates by beta minus emission to the ground state of Ba-137 (5,6 %) and via the 661 keV isomeric level of Ba-137 (94,4 %) which has a half-life of 2,55 min.

Sodium 22 decay scheme The 511 keV photon is expected whenever a radionuclide emits positrons as part of its decay process. e.g. 22 Na. The spectrum will show a gamma-ray at 1274.5 keV, an annihilation peak at 511 keV (from the b +) and probably x-rays from the electron capture. 22 11 Na 11 22 11 Na 11 1cay Scheme De Na-22 disintegrates predominantly to the 1275 keV level of Ne-22 . A very small fraction (0,056 %) disintegrates to the ground state of Ne-22.

It can then be seen that gamma emission at 1294 keV is due to transitions from the excited level at 1.294 MeV to the ground state of K 41 22 Na decay scheme The 511 keV photon is expected whenever a radionuclide emits positrons as part of its decay process.
