Pos(tovane kolege

U petak 14 Decembra preminuo je Art Phelps poznati Americ(ki fizic(ar iz 
fizike niskotemperaturskih plazmi, atomske i molekularne fizike, fizike 
gasnih lasera i mnogo drugih oblasti.

Kod Arta Phelpsa su kao postdoktoranti boravili Brana Jelenkovic' i 
Zoran Petrovic', posetili su ga mnogi od nas(ih istraz(ivac(a a on je 
nas(u zemlju i institut posetio nekoliko puta.  Moz(e se slobodno rec'i 
da je poslednjih 25 godina imao neprekidno saradnju sa nekim od nas(ih 
istraz(ivac(a.

Veliki doprinosi A Phelpsa su pre svega
- formiranje swarm tehnike eksperimentalne, res(enja Boltzmannove 
jednac(ine i analize za odre?ivanje preseka
-kinetika metastabila i pobu?enih stanja u retkim gasovima
-trapovanje emisije svetlosti u gasnim praz(njenjima
-znac(ajan doprinos formiranju ideje o disocijativnoj rekombinaciji i 
zahvatu
-modelovanje kinetike gasnih lasera
-prva merenja na visokim E/N i doprinos brzih neutrala ekscitaciji u 
gasnim praz(njenjima
-osnovi fizike Townsendovih praz(njenja, uticaj naelektrisanja i 
zavisnosti koeficijenta sekundarne emisije od energije jona
-modelovanje sekundarne emisije u gasnim praz(njenjima na osnovu 
podataka za binarne sudare
-multi term prorac(uni funkcije raspodele elektrona
-tumac(enje anomalnog Dopplerovog s(irenja u velikom broju gasova
-odre?ivanje setova preseka za veliki broju gasova (retki gasovi, azot, 
vodonik, deuterijum, kiseonik, SF6, ...) koji ukljuc(uju elektronske 
preseke, preseke za jone i brze neutrale i mnogi drugi.

AV Phelps je prvi dobitnik Will Allis nagrade APSa za gasnu 
elektroniku.  Svoju karijeru zapoc(eo je u Westuinghouse Research 
laboratories a nastavio na Univerzitetu Kolorada i NISTu u laboratoriji  
JILA.

U prilogu vam dostavljamo i pismo koje je Zoran Petrovic' poslao 
administraciji JILAe.

Uz pozdrave

Brana Jelenkovic' i Zoran Lj Petrovic'

Dear Friends at JILA

On the news of passing of Art Phelps I wish to send JILA my letter as
his former postdoc and colleague.

Art was one of the leaders and even founders of the modern physics
of ionized gases and atomic and molecular physics.  His vast knowledge
and experience was always a major source of ideas and inspiration for
all of us. Just reading his footnotes is an amazing experience and a
source of education to his colleagues that is second to none. Art also
had a principle of performing quantitative tests as a necessary part of
research and was never satisfied with his tests until all parts of his
theory were of highest possible quality.

That is why the papers written by him last for many decades and that is
why the papers (a large number of them) still siting in his files are
better than most of the papers published nowadays.

Art has affected lives and careers of all the people that had luck to
have worked with him, he influenced many more and he shaped the whole
field by his knowledge, ideas and strict adherence to ethical and
scientific principles.

With his passing, JILA, scientific community and his colleagues have
lost a lot but with his career we have all gained a
contribution of a truly great man of science.

With regards

Zoran Lj. Petrovic
