photoinization

photoayankaran vaha bhautik prakriya haye jisamen ack paramanu yaa anu key saath ack photon kii antahkriya seey ack aayan banata haye.
cross section.
photon aur paramanu yaa anu key beach harr antahkriya key parinamswarup photoayankaran naheen hoga. photoinization kii sambhavana prajaatiyon key photoinization cross section seey sambandhit haye-ack kaalpanik cross-sectional kshetra key roop mein parikalpit ack aayaneekaran ghatana kii sambhavana. yeh cross section photon kii oorjaa (isaki tarang sankhya key samanupati) aur prajaatiyon koo i maane jaane parr nirbhar kartaa haye.ee. yeh aanvik prajaatiyon kii sanrachana parr nirbhar kartaa haye. anuon key mamle mein, photoinization cross-section kaa anuman ground-state anu aur lakshya aayan key beach frank-condon karakon kii jaanch seey lagaaya jaa sakata haye. ise quantum rasayanik software ee kaa upayog karke anu aur sambandhit catayan (post aayaneekaran) key compan kii ganana karke shuru kiya jaa sakata haye.jee. cuchem. aayaneekaran seema seey neeche kii photon urjaaon key liye, photoayankaran cross-section shoonya key karib haye. lekin spandit lejaron key vikas key saath behad teevra, susangat prakaash banaana sambhav hoe gayaa haye jahaan bahu-photon aayaneekaran uttejanaon aur shithilataon key anukramon key madhyam seey hoe sakata haye. aur bhee adhik teevrata (avarakt yaa drishya prakaash key aspas) parr, gair-vikshobhakaari ghatanaaen jaise "baadha daman aayaneekaran" aur "punah vikshepan aayaneekaran" dekhi jaati hain.
bahu-photon aayaneekaran.
aayaneekaran seema seey neeche oorjaa key kaee photon vaastav mein ack paramanu koo aayaneekaran karane key liye apani urjaaon koo jodd sakate hain. yeh sambhavana aavashyak photon kii sankhya key saath teji seey cumm hoe jaati haye, lekin bahut teevra, spandit lejaron kaa vikas abhee bhee ise sambhav banaata haye. vikshobhakaari vyavastha mein (optical aavrittiyon parr lagbhag 1014 doubleu/semi2 seey cumm), "aine" photon koo avashoshit karane kii sambhavana lazer-prakaash kii teevrata "aaee" key roop mein "aaee" aine "parr nirbhar karati haye. uchch teevrata key liye, yeh nirbharta taba honey vaale assie stark prabhaav key kaaran amaanya hoe jaati haye.
anunaad-vardhit bahu-photon aayaneekaran (rampy) ack takneek haye joe parmaanuon aur chhote anuon kii spectroscopy parr lagu hoti haye jisamen ack tunable lazer kaa upayog ack uttejit madhyavarti sthiti taka pahunchane key liye kiya jaa sakata haye.
seema seey oopar aayaneekaran (ati) bahu-photon aayaneekaran kaa ack vistaar haye jahaan paramanu koo aayaneekaran karane key liye vaastav mein aavashyak photon seey bhee adhik avashoshit hotey hain. atirikt oorjaa jaari electron koo kewal-oopar seema aayaneekaran key samanya mamle kii tulanaa mein uchch gatij oorjaa detee haye. adhik sateek roop seey, pranali key photoelectron spectrum mein kaee shikhar honge joe photon urjaaon dwara alag kiye jaate hain, yeh ingit kartaa haye kii utsarjit electron mein samanya (photon kii sabse cumm sambhav sankhya) aayaneekaran mamle kii tulanaa mein adhik gatij oorjaa hoti haye. lakshya seey chhode gaye electrons mein lagbhag photon-oorjaa kii ack purnank sankhya hogi joe adhik gatij oorjaa pradaan karati haye.
surang aayaneekaran.
jaba yaa tou lazer kii teevrata koo aur badhaaya jaataa haye yaa usa shasson kii tulanaa mein ack lambi tarang dairdhya lagu kii jaati haye jisamen bahu-photon aayaneekaran hotaa haye, tou ack ardh-sthir drishtikon kaa upayog kiya jaa sakata haye aur isake parinamswarup paramanu kshamata iss tarah seey vikrit hoe jaati haye kii ack baadhya avastha aur nirantarta avasthaon key beach kewal ack apekshaakrit cumm aur sankeern baadha bunny rahati haye. taba, electron surang banaa sakata haye yaa badee vikritiyon key liye iss baadha koo door curr sakata haye. inn ghatnaaon koo kramshah surang aayaneekaran aur over-dha-barrier aayaneekaran kahaa jaataa haye.
