A+γ*→n+A*
A+γ*→n+n+A*
などの、1つ又は2つの中性子の生成であり、ここで、γ*は、電子散乱からの仮想光子であり、A*は、原子核壊変生成物を表す。もちろん、前記反応に対応する原子核崩壊反応(breakup reaction)及び実際の光子からの2つの中性子生成反応も、継続的に関心及び研究の対象である。
通常、GDRのは、重い原子核では(10〜20)MeVの範囲にあり、軽い原子核では(15〜25)MeVの範囲にある。
15MeV<E<25MeV。
GDRのエネルギーの詳細な実験概要[9]は、様々な用途で利用可能である。
γ+63Cu→63Cu*→n+62Cu
γ+65Cu→65Cu*→n+64Cu
同様に、テフロンの、さもなければ安定している天然に生じる同位体の、以下の反応による医学的に有用な炭素及びフッ素の放射性同位体への光壊変がある。
γ+12C→12C*→n+11C
γ+19F→18F*→n+18F
LINAC電子源から入射する、測定された光子エネルギーの関数としての、任意の単位でのテフロンの光子吸収率は、以下の図2のスペクトルアナライザのグラフに示されている。
63Cu:安定、天然濃度=69.15%、Z=29、N=34、JP=3/2−、
65Cu:安定、天然濃度=30.85%、Z=29、N=36、JP=3/2−。
ここで、ES相互作用を使用したGDRを介して生成され得る、関心のある2つの半減期が短い同位体がある。62Cu及び64Cuである。64Cuは、核医学及び撮像において頻繁に使用される放射性同位体(RI)のうちの1つである。
62Cu:不安定、半減期=9.67分、Z=29、N=35、JP=1+
β+放出によって62Niに崩壊する、
64Cu:不安定、半減期=12.7時間、Z=29、N=35、JP=1+
β+放出(61%)によって64Niに崩壊し、β−放出(39%)によって64Znに崩壊する。
本発明の一態様によれば、電子装置を使用して、1つの光子を交換するGDRを介して、上記のRIを生成する方法及びシステムが、概略的に以下のように提案されている。
γ+63Cu→63Cu*→62Cu+n
γ+65Cu→65Cu*→64Cu+n

次に、板が未知の材料でできているシステム200で、同位体サンプル板130として役立ち得る可能性がある、(3)枚の板を分析する方法について説明する。目標は、NaI検出器を使用して、(3)枚の板の内部の材料を見つけることである。(3)枚の未知のプレートのそれぞれは、(24)時間、次々に検出器、たとえば電子加速器100の前に置かれる。検出器の前に何も置かない測定での経験から、このプローブには、通常の(天然の)背景以外の汚染物質は含まれていないと言える。次いで、未知の板(1、2、及び3)のそれぞれに、アプリケータ15×15を使用して、22MeVの広い電子ビームの下で(10)分間、1000MUが照射される。その後、板は(24)時間、次々に、検出器の前に置かれた。同位体の消滅ピークに集中し、消滅ピークにズームして、スペクトルの消滅ピークの特別な部分で発生するイベントの、時間依存性を評価する方策を選択した。
