The style of the Research of Hungarian Scientists in Science and Technology

Regarding the International Collaboration

Outline

1. Possibility for small countries andexamples from our practice

2. Collaborations of ATOMKI and other Hungarian institutes with Japanese

institutions

1. Possibility for small countries

and examples from our practice

5

a.Large, expensive equipments are missing in these countries

accelerators, telescopes, satellites etc.

b. The way to be followed is to construct original, unique smaller instruments to be used at large

equipments abroad to work out measuring programs for the large equipments on the basis of original ideas the collaboration is the key word

6

c. It is characteristic how the nuclear physics research was start in Debrecen by Professor A. Szalay (1909-1987), the founder of the Debrecen physics research school

in 1938 the 27Al(,n)30P was studied[1] in Vienna (Institute für Radiumforschung) but the simple at the same time original apparatus was built in Debrecen and was  transported to Vienna

7

- 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, by means of a financial support from the Academy of Sciences, Budapest”.

Spectroscopy) of Atomic Physics Division of ATOMKI are shown in Table 1.

2. Collaborations of ATOMKI and other Hungarian institutes with Japanese

institutions

16

a. Outset Let us speak on the collaboration

between Japanese and Hungarian institutions in general in the past and

the role of 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

17

- his topic was the same as it was in our group that time i.e. – among others –

internal bremsstrahlung - the “relic” of this first contact a beautiful Japanese doll

18

probably the next step in the Japanese- Hungarian collaboration in general is also connected to our division - at the very beginning of the seventies Professor Sakae Shimizu (Kyoto Univ.) contact us by letter because he knew our

results from the literature - then I. Kádár from our division worked a

year in Prof. Shimizu’s laboratory (1972/73)

19

- 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

20

b. From the seventies more and more intensive collaboration of our division with Shimizu’s laboratory and with other

Japanese institutes has been continuous

a number of results were produced in the seventies in our division in the 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 shown in Fig.1.[2] T. Mukoyama, L. Sarkadi, D. Berényi and E. Koltay, Phys. Letters 67A(1978)180

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

22

our results show the deviation in the case of K/K ratio for N+(2,8 MeV) relative to that

for proton impact. [2-5] it can be explained by the relative

importance of M-shell vacancies in this energy region

the results were used to deduce information about the vacancy configurations of ionized atoms it is an evidence for the importance of direct Coulomb interaction in the multiple ionization process no quantitative theory for the interpretation

d. Japanese and Hungarian collaborations in the spirit which was shown before became very 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 seminars Table 3

e. Future of the Japanese-Hungarian collaboration

• the aim of joint seminars to promote the collaborations

• we strongly hope a even more closer collaboration in 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 to Dr. László GULYÁS
