 ラザフォードE. Rutherford20世紀初頭の原子核物理学の発展を切り開いた大実験物理学者であることはよく知られたことです.1911年のアルファ粒子の金属箔による散乱実験での原子核の発見、1919年の窒素原子核のアルファ粒子による核変換は、今ならばその一つでノーベル賞がもらえる大発見です.彼は1908年にアルファ線がヘリウム原子核であることの発見など業績でノーベル化学賞を受賞している。


その彼が1920年にロンドン王認協会で行ったベーカー講義the Bakerian Lectureでの発言が興味深いものです。(Royal Societyは王立協会と訳されることが多いが、間違いであることは科学史家の板倉さんが前から指摘しています。United States を合州としないで合衆とする間違いに相当する悪訳その一節を引用すると(引用文中の引用符内はラザフォードの言葉)

“----, he also chose to speculate about the possibility of a third major constituent of atoms besides electrons and protons. He spoke of ‘the possible existence of an atom of mass 1 which has zero nuclear charge.’ “  (p.153)

 チャドウィックJ. Chadwickラザフォードの弟子で優秀な実験家だったそうですが、この講演を聴いたことをきっかけに中性子に関心を持ち、ラザフォードと議論をしたようです.彼が後に語った言葉をローズRhodesが引用しています。

“And so,” Chadwick concludes, “it was these conversations that convinced me that the neutron must exist. The only question was how the devil could one get evidence for it, ---. (p. 155)

 ベーカー講義から10年経った1930年に、ドイツのボーテとベッカーW. Bothe and H. Beckerが、アルファ粒子をベリリウムBeに照射したときに起こる奇妙な現象を観測します。”The radiation they had excited from beryllium had more energy than the bombarding alpha particles. ---; they proposed that it came from nuclear disintegration despite the absence of proton. (p. 159).

ボーテ達の”beryllium radiation発見に刺激されて、イギリスではチャドウィックが、フランスではイレーヌとジョリオ夫妻が、同様な実験を始めます。

 1931の春、チャドウィック達は新しい実験データを得ます。”— the radiation from beryllium which was emitted in the same direction as the alpha-particles was more penetrating than the radiation emitted in  a backward direction.“And that, of course,” Chadwick adds, “ was a point which excited me very much indeed, because I thought, Heres the neutron. (p. 160)

 他方、フランスではキュウリー夫妻が新しい発見をし、それを1932118日にフランス科学アカデミーに報告します.”--- their discovery that paraffin wax emitted high-velocity protons when bombarded by beryllium radiation with a title ‘The emission of protons of high velocity from hydrogenous materials irradiated with very penetrating gamma rays.

 この報告が載っている雑誌Compte rendus2月の上旬にロンドンに届き、チャドウィックの目にとまります。彼は早速ラザフォードに話しますが、そのときの様子が記されています。Chadwick writes: [In early February] as I told him [Rutherford] about the Curie-Joliot observation and their views on it, I saw his growing amazement; and finally he burst out ‘I don’t believe it.’ Such an impatient remark was utterly out of character, and in all my long association with him I recall no similar occasion. I mention it to emphasize the electrifying effect of the Curie-Joliot report. Of course, Rutherford agreed that one must believe the observations; the explanation was quite another matter.” (p. 162)

 彼らは早速キューリー夫妻の実験を再試します.そして放出される陽子のエネルギーの大きさが、キューリー夫妻の説明のようにガンマ線によると考えたのでは説明できないことを認識します。It is evident that we must either relinquish [abandon] the application the conservation of energy and momentum in these collisions or adopt another hypothesis about the nature of the radiation. When they read that sentence the Joliot-Curies were deeply and properly chagrined.

    If we suppose that the radiation is not a [gamma] radiation, but consists of particles of mass very nearly equal to that of the proton, all the difficulties connected with the collisions disappear, both with regard to their frequency and to the energy transfer to different masses. In order to explain the great penetrating power of the radiation we must further assume that the particle has no net charge. --- We may suppose it [to be] the neutron discussed by Rutherford in his Bakerian Lecture of 1920.” (p. 163)

 チャドウィックは研究所の仕事をこなしながら、この実験を10日ほどで纏め、1932217日にNatureに投稿します。”He titled that report published as a letter to the editor, Possible existence of a neutron. ---But there was no doubt whatever in my mind or I should not have written the letter.” (p. 163)

Naval Research Laboratory Report NRL/MR/6320—01-8526

M.H. Miles, M. Fleischmann and M.A. Imam, Calorimetric Analysis of a Heavy Water Electrolysis Experiment Using a Pd-B Alloy Cathode


   This study involves the palladium-boron alloy materials prepared at the Naval Research Laboratory (NRL) by Dr. M. Ashraf Imam (see NRL/MR/6170-96-7803, January 9, 1996). This new material was developed as part of a collaborative program with NRL: and the Naval Air Warfare Center Weapons Division (NAWCED), China Lake, that was funded by the Office of Navel Research (ONR). Studies at NAWCED showed that the best reproducibility for excess power was obtained using the palladium-boron materials supplied by NRL (seen NAWCWPNS TP 8302, September 1996). The new experimental studies described in this report were conducted by Dr. Melvin H. Miles at the New Hydrogen Energy (NHE) laboratory in Sapporo, Japan. Dr. Melvin H. Miles received a six months appointment as a Guest Researcher sponsored by the New Energy Development Organization (NEDO) of Japan. Dr. Melvin H. Miles expresses his appreciation to Dr. N. Asami and Mr. K. Matsui for providing him with this research opportunity. This experiment was conducted in a special Dewar-type calorimetric cell silvered at the top that was developed by Drs. Martin Fleischmann and Stanley Pons. The detailed analysis of the experimental data presented in this report was conducted by Dr. Martin Fleischmann. An independent method of data analysis developed by Dr. Melvin H. Miles while he was in Japan was presented in his DEDO Final Report and shows similar trends for the excess heat effect.


3)  WN’s comment on it.アメリカ物理学会のB. Parkが早速Miles達の論文に狂信的な反応を示してくれました。これが科学的態度と呼べるのでしょうか.

WHAT'S NEW   Robert L. Park   Friday, 20 April 01   Washington, DC

3. COLD FUSION: MAYBE ONE MORE STUDY WILL CLEAR THINGS UP.  Or may be not. We hear often these days from cold fusion believers

about the great progress that has been made in cold fusion.  We

will hear it again on April 30, at the APS meeting. 

This week,

WN received a long report from the Naval Research Laboratory.  It

was dated March 26, 2001, just three days after the anniversary

of the 1989 cold fusion press conference in Salt Lake City.  The

report was about a Pons and Fleischmann kind of experiment: an

"open" electrolysis study of excess heat in the electrolysis of

heavy water, using a Pd-B alloy cathode. One of the authors is

none other than Martin Fleischmann.  How appropriate.  


years ago at this time, the news was about the unreliability of

closed calorimetry experiments.  Twelve years later, cold fusion

research is still struggling with the same point.  Progress?

この結果の著者らによる解釈は、Pd不純物としてそれぞれ100 ppm, 50 ppmAgRhを含んでいるので、それが表面に拡散析出したのである。」としています。しかし、G. Alefeld and J. Voelkl, Hydrogen in Metals II, の総合報告 B. Baranowski, Metal-Hydrogen System at High Hydrogen Pressures ではPdRh合金でRh40%までの場合の実験結果が記されており、極微量のRh含有量のうちの30%(著者らの計算による)が表面に集まってくるようなことは、納得できない解釈です。
