Kana yakasununguka munzvimbo inotonhora, mamorekuru anozongoerekana atonhora nekudzikisa kutenderera kwayo uye kurasikirwa nesimba rekutenderera mu quantum transitions.Physicists vakaratidza kuti iyi inotenderera inotonhora nzira inogona kukurumidza, kudzikiswa kana kudzoserwa nekupokana kwemamorekuru ane zvikamu zvakapoteredza. .googletag.cmd.push(basa() {googletag.display('div-gpt-ad-1449240174198-2′); });
Vatsvakurudzi veMax-Planck Institute for Nuclear Physics kuGermany neColumbia Astrophysical Laboratory nguva pfupi yadarika vakaita ongororo ine chinangwa chekuyera huwandu hwekuchinja kwehuwandu hunokonzerwa nekudhumhana pakati pemamorekuru nemaerekitironi. Zvavakawana, zvakaburitswa muPhysical Review Letters, zvinopa humbowo hwekutanga hwekuyedza. yereshiyo iyi, iyo yakambofungidzirwa chete nedzidziso.
"Apo maerekitironi nemaioni emamorekuru aripo mugasi risina simba reionized, huwandu hwakaderera hwehuwandu hwemamorekuru hunogona kuchinja panguva yekudhumhana," Ábel Kálosi, mumwe wevaongorori vakaita chidzidzo ichi, akaudza Phys.org. process iri muinterstellar clouds, uko kucherechedzwa kunoratidza kuti mamorekuru akanyanya mumatunhu awo akaderera equantum.Kukwezvwa kuri pakati pemaerekitironi akachajiwa zvisina kunaka uye maeroni akachajiwa zvakanaka anoita kuti kudhumhana kwerekitironi kuve kwakanyanya kushanda zvakanaka.
Kwemakore, nyanzvi dzefizikisi dzanga dzichiedza kuona kuti maerekitironi akasununguka akabatana sei nemamorekuru panguva yekudhumhana uye pakupedzisira anochinja mamiriro avo ekutenderera.Zvisinei, kusvika parizvino, kufanotaura kwavo kwedzidziso hakuna kuedzwa mune yekuyedza mamiriro.
"Kusvika ikozvino, hapana kuyerwa kwakaitwa kuona chokwadi chekuchinja kwesimba rekutenderera kwehuwandu hwemagetsi uye tembiricha yakapihwa," anotsanangura kudaro Kálosi.
Kuti vaunganidze chiyero ichi, Kálosi nevamwe vake vakaunza mamorekuru akachajwa ari ega kuti abatane nemaerekitironi patembiricha yakatenderedza 25 Kelvin.
Mukuedza kwavo, vatsvakurudzi vakashandisa cryogenic kuchengetedza mhete paMax-Planck Institute for Nuclear Physics muHeidelberg, Germany, yakagadzirirwa mhando-selective molecular ion beams. inobviswa zvakanyanya kubva kune chero mamwe magasi ekumashure.
"Muchindori che cryogenic, maion akachengetwa anogona kutonhodzerwa nemhepo kusvika pakupisa kwemadziro eringini, zvichiita kuti maion anozadzwa nemazinga akaderera," anotsanangura kudaro Kálosi. iyo chete yakashongedzerwa nechaicho chakagadzirwa simbi yeelectron inogona kunangidzirwa pakubata nemaioni emamolecular.Ioni dzinochengetwa kwemaminetsi akati wandei murin'i iyi, laser inoshandiswa kubvunzurudza simba rekutenderera remaioni emamorekuru."
Nekusarudza chaiyo optical wavelength yeprobe laser yayo, timu inogona kuparadza chikamu chidiki chemaioni akachengetwa kana simba ravo rekutenderera richienderana newavelength iyoyo.Vakabva vaona zvidimbu zvemamorekuru akavhiringika kuti vawane anonzi masaini espectral.
Chikwata chakaunganidza zviyero zvavo muhupo uye kusavapo kwekupokana kwemaelectron.Izvi zvakavabvumira kuona shanduko muhuwandu hwakachinjika pasi pemamiriro ekushisa akaderera akaiswa mukuyedza.
"Kuyera maitiro ekutenderera-kuchinja-kuchinja mamiriro ehurumende, zvakakosha kuve nechokwadi kuti kunongova nechiyero chakaderera chesimba rekutenderera muion yemorekuru," akadaro Kálosi. mavhoriyamu, uchishandisa cryogenic kutonhora kusvika kune tembiricha iri pasi pekamuri tembiricha, iyo inowanzova pedyo ne300 Kelvin.Mune iyi vhoriyamu, mamorekuru anogona kuparadzaniswa kubva kune akajairika mamorekuru, Infrared thermal radiation yenharaunda yedu. "
Mukuedza kwavo, Kálosi nevamwe vake vakakwanisa kuwana mamiriro ekuedza umo kudhumhana kwemagetsi kunotonga shanduko yemagetsi. Nekushandisa maerekitironi akakwana, vaigona kuunganidza zviyero zvemaerekitironi neCH+ mamorekuru ayoni.
"Takaona kuti electron-induced rotational transition rate inofanana nekufanotaura kwekare," Kálosi akadaro." Zviyero zvedu zvinopa bvunzo yekutanga yekufungidzira kwagara kuripo.Isu tinofungidzira kuti maverengero emangwana anozonyanya kutarisisa pamusoro pezvinobvira kudhumhana kwemagetsi pane yakaderera-chikamu chesimba munzvimbo inotonhora, yakasarudzika quantum masisitimu. "
Pamusoro pekusimbisa fungidziro yekufungidzira mune yekuedzwa kwekutanga, basa rechangobva kuitika reboka iri revatsvaguri rinogona kunge riine zvakakosha patsvakiridzo.Semuyenzaniso, zvavakawana zvinoratidza kuti kuyera electron-induced rate of change in quantum energy levels inogona kuva. kwakakosha pakuongorora zviratidzo zvisina kusimba zvemamorekuru ari muchadenga akaonekwa neredhiyo teresikopu kana kemikari reactivity mumaplasma matete uye anotonhora.
Mune ramangwana, bepa iri rinogona kugadzira nzira yezvidzidzo zvitsva zvedzidziso zvinonyatso funga nezve mhedzisiro yekudhumhana kweerekitironi pakubata kwesimba rekutenderera kwehuwandu hwemagetsi mumamorekuru anotonhorera. zvinokwanisika kuita ongororo dzakadzama mumunda.
"Mumhete yekuchengetera yecryogenic, tinoronga kuunza tekinoroji yelaser yekuongorora kutenderera kwesimba remamwe marudzi ediatomic uye polyatomic molecular," anowedzera Kálosi." .Zviyero zvemurabhoritari zverudzi urwu zvicharamba zvichiwedzerwa, kunyanya mukuongorora nyeredzi uchishandisa maobservatories ane simba akadai seAtacama Large Millimeter/Submillimeter Array muChile.”
