  1. 3rd Japan-Hungary Joint Seminar on Physics in Modern Science and Technology Progress in Science and Technology with Particle and Photon Beams October 8-12, 2007, Debrecen – Szeged - Budapest The style of the Research of Hungarian Scientists in Science and Technology Regarding the International Collaboration DÉNES BERÉNYI Institute of Nuclear Research of the Hungarian Academy of Sciences Opening address

  2. The style of the Research of Hungarian Scientists in Science and Technology • Regarding the International Collaboration • Outline • Possibility for small countries and • examples from our practice • 2. Collaborations of ATOMKI and otherHungarian institutes with Japanese • institutions

  3. Possibility for small countries • and examples from our practice

  4. Large, expensive equipments are missing inthese countries •  accelerators, telescopes, satellites etc. • b. The way to be followed is •  to construct original, unique smaller • instrumentsto be used at large • equipments abroad •  to work out measuring programs forthe • large equipmentson the basis of original • ideas •  the collaborationis the key word

  5. c.It is characteristic how the nuclear physics research was start inDebrecen by ProfessorA. Szalay (1909-1987), the founder of theDebrecen physicsresearch school  in 1938 the 27Al(,n)30P was studied[1] in Vienna (Institute fürRadiumforschung)but the simple at the same time original apparatus was built inDebrecen and was transported to Vienna

  6. Szalay’s statement in this respect • Szalay wrote at the end of the paper concerned • „The apparatus has been built in the Institute of Physics, Debrecen, Hungary, bymeans of a financial support from the Academy of Sciences, Budapest”. • [1]A. Szalay, Nature 141(1938)972

  7. d.As an example the present foreign collaborations of the two sections (Atomic Collisions and Electron Spectroscopy) of Atomic Physics Division of ATOMKI areshown in Table 1.

  14. Collaborations of ATOMKI and otherHungarian institutes with Japanese • institutions

  15. a. Outset Let us speak on the collaboration betweenJapanese and Hungarian institutions in general in the past and the roleof our institute in that  probably the first contact was as follows - Yujiro Koh (Osaka City University) visit Hungary and our Institute in the first half of sixties of the last century

  16. - his topic was the same as it was in our group that time i.e. – among others – internalbremsstrahlung -the “relic” of this first contact a beautiful Japanese doll

  17.  probably the next step in the Japanese-Hungarian collaboration in general is also connected to our division - at the very beginning of the seventiesProfessor Sakae Shimizu(KyotoUniv.) contact us by letter because he knew our resultsfrom the literature - then I. Kádár from our division worked a year in Prof. Shimizu’slaboratory(1972/73)

  18. -as a next step Takeshi Mukoyama worked nearly a year in our division  from Prof. Sakae Shimizu’s laboratory - in T. Mukoyama’s carrier this sojourn was decisive as he mentioned it several times

  19. b. From the seventies more and more intensive collaboration of our division with Shimizu’s laboratory andwith other Japanese institutes has beencontinuous a number of results were produced in the seventies in ourdivision inthe frame of the collaboration concerned [2-5] an example is the results on the X-ray production in atomic collision   processes[2]. A characteristic diagram of results is shownin Fig.1. [2] T. Mukoyama, L. Sarkadi, D. Berényi and E. Koltay, Phys. Letters 67A(1978)180 [3] D. Berényi, G. Hock, S. Ricz, B. Schlerk and A. Valek, J: Pys. B. Atom. Molec. Phys. 11(1978)709 [4] D. Berényi, Bull. of the Instr. for Chem. Res., Kyoto University 57(1978)139 [5] T. Mukoyama, I. Sarkadi, D. Berényi and E. Koltay, J. Phys. B: Atom. Molec. Phys. 13(1980)2773

  20. Fig.1. K/K ratios for N+ ions relative to those for protons as function of E/UM Here E is the incident energy of the projectile,  is the mass of the projectile and UM is the average binding energy on the M shell concerned [2] 21

  21. our results show the deviation in the caseofK/K ratio for N+(2,8 MeV)relative tothat for proton impact. [2-5] it can be explained by the relativeimportance of M-shell vacancies inthis energy region the results were used to deduceinformation about the vacancyconfigurationsof ionized atoms it is an evidence for the importance ofdirect Coulomb interaction in the multiple ionization process no quantitative theory for the interpretation

  22. c. Collaborations of the whole ATOMKI with Japanese institutes is shown in Table 2

  23. Table 2. Collaborations of the whole ATOMKI with Japanese Institutions* *Only the contact persons are indicated

  25. Table 2 (continued)

  26. d. Japanese and Hungarian collaborations in the spirit which was shownbefore becamevery intensive not only in the case of our Institute last time the collaboration among Hungarian and Japanese institutes in general have become very widespread it is well demonstrated by the joint JSPS-HAS seminarsTable 3

  27. Table 3 Japan-Hungary Joint Seminars

  28. Future of the Japanese-Hungarian collaboration • the aim of joint seminars to promote the collaborations • we strongly hope a even more closer collaborationin general and in our field in particular as a result of the present joint seminar • May I express my sincere thank for the help in the preparation of this talk to several persons but first of all toDr. László GULYÁS
